1 00:00:00,160 --> 00:00:01,320 Speaker 1: Welcome to our time together. 2 00:00:01,439 --> 00:00:02,759 Speaker 2: It is so good to be here with you. 3 00:00:03,279 --> 00:00:06,160 Speaker 1: As you settle in, just take a moment to look 4 00:00:06,240 --> 00:00:09,640 up with us. Imagine we are just two friends sitting outside, 5 00:00:10,199 --> 00:00:15,119 leaning back under this incredibly vast, dark, starlit sky. 6 00:00:15,480 --> 00:00:17,879 Speaker 2: Yeah, just a quiet, safe space. 7 00:00:17,719 --> 00:00:21,559 Speaker 1: Exactly quiet exploration. Wrap yourself in a soft blanket, take 8 00:00:21,600 --> 00:00:25,399 a deep breath, and let your busy mind just sort 9 00:00:25,399 --> 00:00:28,239 of drift for a while. We are in the peaceful 10 00:00:28,280 --> 00:00:31,280 space of the quantum Curious. 11 00:00:31,160 --> 00:00:33,640 Speaker 2: And tonight we are going to look at the invisible, 12 00:00:33,960 --> 00:00:35,399 quiet threads. 13 00:00:35,039 --> 00:00:39,479 Speaker 1: That connect the universe, the threads that connect everything. Really tonight, 14 00:00:39,479 --> 00:00:42,679 we are gently drifting through the concept of quantum entanglement. 15 00:00:42,920 --> 00:00:46,320 We're going to explore what Albert Einstein maybe got a 16 00:00:46,320 --> 00:00:50,119 little wrong and how these incredibly delicate, invisible connections are 17 00:00:50,600 --> 00:00:53,520 slowly weaving the future of a quantum Internet. 18 00:00:53,640 --> 00:00:55,840 Speaker 2: And just to reassure you as you're listening, there is 19 00:00:55,960 --> 00:00:58,399 absolutely no math to memorize here, oh. 20 00:00:58,280 --> 00:01:00,000 Speaker 1: Definitely not no tests, no quizes. 21 00:01:00,240 --> 00:01:02,560 Speaker 2: Right, we are just going to share the profound beauty 22 00:01:02,640 --> 00:01:05,000 behind the science, the why of it all. We're going 23 00:01:05,040 --> 00:01:07,519 to take it at a very slow, meditative pace. 24 00:01:07,920 --> 00:01:10,560 Speaker 1: I love it so let's start with those invisible threads. 25 00:01:11,319 --> 00:01:15,359 What exactly is quantum entanglement like at its most gentle, 26 00:01:15,680 --> 00:01:16,760 basic level. 27 00:01:16,640 --> 00:01:19,719 Speaker 2: Well, at its core, it's a profound link. It happens 28 00:01:19,719 --> 00:01:23,200 when two or more particles, like tiny packets of light 29 00:01:23,319 --> 00:01:26,959 called photons or you know, little electrons, becomes so deeply 30 00:01:26,959 --> 00:01:30,359 connected that you literally cannot describe one without describing the. 31 00:01:30,319 --> 00:01:32,120 Speaker 1: Other, no matter how far apart they drift. 32 00:01:32,280 --> 00:01:34,879 Speaker 2: Exactly, they could drift to opposite ends of the universe, 33 00:01:34,879 --> 00:01:38,560 but they are still dancing together. But to really see it, 34 00:01:38,599 --> 00:01:41,079 we have to talk about a concept called superposition. 35 00:01:41,359 --> 00:01:45,439 Speaker 1: Right, superposition, which sounds complicated, but. 36 00:01:45,879 --> 00:01:48,640 Speaker 2: It's not really. Imagine you have a silver coin and 37 00:01:48,680 --> 00:01:50,120 you toss it high into the air. 38 00:01:50,359 --> 00:01:52,040 Speaker 1: Okay, I can see it as it spins. 39 00:01:52,079 --> 00:01:56,319 Speaker 2: It's just this beautiful, shimmering blur of silver. It isn't 40 00:01:56,319 --> 00:01:59,959 heads and it isn't tails. It's this soft, endless blur 41 00:02:00,239 --> 00:02:02,239 of both possibilities. 42 00:02:01,519 --> 00:02:04,079 Speaker 1: At once, just hovering in that state of potential. 43 00:02:04,319 --> 00:02:06,439 Speaker 2: Right, it only becomes heads or tails in the very 44 00:02:06,519 --> 00:02:08,639 moment it softly lands in the palm of your hand. 45 00:02:08,719 --> 00:02:12,319 That's superposition existing in multiple states, you know, until it's 46 00:02:12,319 --> 00:02:13,599 generally asked to choose one. 47 00:02:13,800 --> 00:02:17,039 Speaker 1: I love that image. And so entanglement is when you 48 00:02:17,120 --> 00:02:18,520 have two of these spinning coins. 49 00:02:18,639 --> 00:02:20,560 Speaker 2: Yeah, but they are linked in what we call a 50 00:02:20,599 --> 00:02:24,719 singlet state, which is perfectly anti correlated. 51 00:02:24,240 --> 00:02:26,879 Speaker 1: Anti correlated, like a mirror image. Just like that. 52 00:02:27,439 --> 00:02:32,680 Speaker 2: Imagine two ballet dancers in a vast, quiet, softly lit ballroom. 53 00:02:32,960 --> 00:02:38,199 They're moving in perfect mirrored synchrony. When one dancer gracefully 54 00:02:38,240 --> 00:02:42,199 dips low to the floor, the other dancer instinctively instantly 55 00:02:42,280 --> 00:02:42,800 rises up. 56 00:02:43,120 --> 00:02:45,759 Speaker 1: So if one coin lands on heads, the other one 57 00:02:45,840 --> 00:02:46,360 is tails. 58 00:02:46,759 --> 00:02:50,560 Speaker 2: Always. But people didn't always believe this was special. There's 59 00:02:50,599 --> 00:02:53,560 this famous story from physicist John Bell about a man 60 00:02:53,680 --> 00:02:57,639 named Bertman ah Burton socks, yes, Bertlin socks. So Bertleman 61 00:02:57,800 --> 00:03:01,039 was known for always always wearing this match socks every 62 00:03:01,039 --> 00:03:03,280 single day, every day. So if you look down and 63 00:03:03,280 --> 00:03:05,439 saw a bright pink sock on his left foot, you 64 00:03:05,439 --> 00:03:08,080 would instantly know, without even looking that the right foot 65 00:03:08,120 --> 00:03:09,000 is not pink right. 66 00:03:09,000 --> 00:03:11,280 Speaker 1: You'd know right away there's no magic there. The socks 67 00:03:11,280 --> 00:03:13,039 were already pink and green when you put them on 68 00:03:13,039 --> 00:03:14,240 in his quiet bedroom. 69 00:03:13,919 --> 00:03:16,280 Speaker 2: That morning, exactly. And that is what a lot of 70 00:03:16,280 --> 00:03:19,280 people thought entanglement was. They thought the particles were just 71 00:03:19,360 --> 00:03:22,759 like socks, with their colors already decided before they drifted apart. 72 00:03:22,800 --> 00:03:23,879 Speaker 1: But that's not true, is it. 73 00:03:24,240 --> 00:03:27,400 Speaker 2: No, it's far more magical than that. The color of 74 00:03:27,439 --> 00:03:30,560 these quantum socks or their spin isn't decided at all. 75 00:03:30,840 --> 00:03:34,280 There are still spinning coins. The state isn't chosen until 76 00:03:34,319 --> 00:03:36,800 the exact quiet moment you look at them. 77 00:03:37,120 --> 00:03:40,159 Speaker 1: Wait, really, but how, I mean, how does the second 78 00:03:40,159 --> 00:03:43,120 particle know to choose the opposite state at that exact 79 00:03:43,159 --> 00:03:46,120 same moment, even if it's drifting somewhere across the galaxy. 80 00:03:46,199 --> 00:03:49,280 Speaker 2: That is the beautiful mystery, and it is exactly what 81 00:03:49,360 --> 00:03:51,439 gave Albert Einstein so much discomfort. 82 00:03:51,599 --> 00:03:54,000 Speaker 1: I can imagine, because it feels like a trick, right yeah. 83 00:03:54,039 --> 00:03:57,680 Speaker 2: In nineteen thirty five, Einstein, along with Boris Podolski and 84 00:03:57,759 --> 00:04:02,520 Nathan Rosen, wrote this very famous paper, the EPR Paradox, 85 00:04:03,400 --> 00:04:07,159 and Einstein was deeply, deeply unsettled by this idea. He 86 00:04:07,199 --> 00:04:10,080 famously called it a spooky action at a distance. 87 00:04:10,360 --> 00:04:13,639 Speaker 1: Spooky action because he liked things to be neat and predictable. 88 00:04:13,680 --> 00:04:16,839 Speaker 2: He did he believed in this concept called local realism. 89 00:04:16,920 --> 00:04:19,759 Speaker 1: Local realism. Let's paint a picture, of that for our listener. 90 00:04:20,000 --> 00:04:25,319 Speaker 2: Sure, think of a still quiet pond at twilight. If 91 00:04:25,360 --> 00:04:28,439 you gently drop a small pebble into the water, it 92 00:04:28,480 --> 00:04:30,800 only affects the water immediately touching it. 93 00:04:31,040 --> 00:04:34,720 Speaker 1: Right, the ripples just slowly, peacefully travel outward. 94 00:04:34,959 --> 00:04:39,959 Speaker 2: Exactly, they travel at a set predictable speed. The pebble 95 00:04:40,000 --> 00:04:42,079 doesn't instantly cause a splash on the other side of 96 00:04:42,079 --> 00:04:47,160 the world. That's local realism. Objects only influence their immediate surroundings, 97 00:04:47,399 --> 00:04:49,959 and they exist definitively whether we look at them or not. 98 00:04:50,240 --> 00:04:52,920 Speaker 1: The pebble is there, the water is there. It's comforting. 99 00:04:53,120 --> 00:04:56,360 Speaker 2: Really, it is very comforting. So to explain the strange 100 00:04:56,519 --> 00:05:00,319 quantum connection without breaking his comforting rules, Einstein's said there 101 00:05:00,399 --> 00:05:01,879 must be hidden variables. 102 00:05:02,000 --> 00:05:04,360 Speaker 1: Hidden variables like a secret code. 103 00:05:04,439 --> 00:05:08,439 Speaker 2: Yeah, imagine a tiny, secret, invisible instruction manual tucked inside 104 00:05:08,480 --> 00:05:12,639 each particle. And this manual contains predetermined quiet rules for 105 00:05:12,759 --> 00:05:14,279 every possible situation. 106 00:05:14,720 --> 00:05:16,879 Speaker 1: So Einstein was hoping that the particles already knew what 107 00:05:16,879 --> 00:05:18,120 they were going to do. They war to blur. They 108 00:05:18,120 --> 00:05:19,920 just had a secret manual we couldn't read. Yet. 109 00:05:20,160 --> 00:05:23,199 Speaker 2: He desperately wanted the universe to be predictable. He wanted 110 00:05:23,240 --> 00:05:27,439 causality to be preserved. Where nothing, absolutely nothing travels faster 111 00:05:27,519 --> 00:05:28,319 than the speed of light. 112 00:05:28,439 --> 00:05:30,319 Speaker 1: It's a very peaceful way to look at the universe, 113 00:05:30,439 --> 00:05:32,439 especially when you're just trying to relax and make sense 114 00:05:32,480 --> 00:05:34,839 of things. But not everyone agreed with them, did they. 115 00:05:35,199 --> 00:05:41,240 Speaker 2: No? Irwin Schrodinger, for one, saw this strange connection entirely differently. 116 00:05:41,720 --> 00:05:46,839 He actually coined this beautiful German word for shrankoon for shrankom. 117 00:05:47,240 --> 00:05:50,480 Speaker 1: It sounds so poetic, which means entanglement. 118 00:05:50,879 --> 00:05:53,240 Speaker 2: Yes, he saw that the universe was asking us to 119 00:05:53,360 --> 00:05:56,959 gently let go of that classical comfort blanket, to accept 120 00:05:56,959 --> 00:05:59,680 that things are deeply fundamentally intertwined in a way we 121 00:05:59,720 --> 00:06:00,639 can't always see. 122 00:06:00,879 --> 00:06:02,839 Speaker 1: But how do we ever figure out who is right? 123 00:06:03,439 --> 00:06:06,879 If Einstein's instruction manuals are invisible and hidden, how do 124 00:06:06,920 --> 00:06:07,879 you prove they aren't there? 125 00:06:07,959 --> 00:06:09,600 Speaker 2: Well, we had to wait quite a while, But then 126 00:06:09,800 --> 00:06:11,439 a man named John Klauser came along. 127 00:06:11,639 --> 00:06:14,680 Speaker 1: Oh the scrap metal experiment. I love this story. So 128 00:06:14,800 --> 00:06:17,160 this is around nineteen sixty nine and then nineteen seventy 129 00:06:17,199 --> 00:06:19,360 two at Caltech right. 130 00:06:19,879 --> 00:06:23,439 Speaker 2: Clauser took a brilliant mathematical theorem written by John Bell. 131 00:06:24,279 --> 00:06:27,040 Bell had proven on paper that this entanglement couldn't be 132 00:06:27,079 --> 00:06:29,160 explained by hidden instruction manuals. 133 00:06:29,199 --> 00:06:31,160 Speaker 1: So Klauser wanted to see it in the real world. 134 00:06:31,240 --> 00:06:33,560 Speaker 2: He did, and he was actually advised not to do it. 135 00:06:33,560 --> 00:06:35,680 People told him it was a waste of time. But 136 00:06:35,800 --> 00:06:40,319 he was driven by this pure quiet curiosity and honestly 137 00:06:40,480 --> 00:06:42,600 a secret hope that Einstein was right. 138 00:06:42,720 --> 00:06:45,079 Speaker 1: He wanted the clear stuff in the box universe too. 139 00:06:45,360 --> 00:06:48,800 He thought Neil's Bore's quantum ideas were a bit too muddy. 140 00:06:49,120 --> 00:06:51,040 Speaker 2: Yeah, he wanted to find the gears of the clock. 141 00:06:51,319 --> 00:06:54,680 So he built this groundbreaking apparatus. But he didn't have 142 00:06:54,720 --> 00:06:57,680 a pristine, expensive lab. He built it out of leftover 143 00:06:57,720 --> 00:06:59,319 physics departments scrap metal. 144 00:06:59,600 --> 00:07:02,279 Speaker 1: Just picture him in a quiet basement, piecing together these 145 00:07:02,399 --> 00:07:04,600 forgotten bits of metal and glass. 146 00:07:04,319 --> 00:07:09,000 Speaker 2: Exactly, heating up calcium atoms until they softly glowed, releasing 147 00:07:09,040 --> 00:07:12,240 these paired, entangled photons, and he measured them. 148 00:07:12,360 --> 00:07:14,000 Speaker 1: And what did this scrap metal tell him? 149 00:07:14,120 --> 00:07:16,720 Speaker 2: It told him the magic was real. The universe really 150 00:07:16,800 --> 00:07:21,519 does have spooky action. Secret instruction manuals don't exist. Local 151 00:07:21,560 --> 00:07:24,079 realism is just not the whole story of our reality. 152 00:07:24,399 --> 00:07:28,399 Speaker 1: That is just wow. The poetic justice of that. He 153 00:07:28,439 --> 00:07:32,199 wanted to prove Einstein wright, but his curiosity led him 154 00:07:32,199 --> 00:07:33,560 to prove the magic instead. 155 00:07:33,680 --> 00:07:35,920 Speaker 2: It's beautiful, isn't it, and it eventually earned him the 156 00:07:36,079 --> 00:07:39,600 Wolf Prize and much later the twenty twenty two Nobel Prize, 157 00:07:39,680 --> 00:07:42,399 which he shared with Alene Aspect and Anton's silenk. 158 00:07:42,839 --> 00:07:45,839 Speaker 1: But wait, if this connection is real and the coin 159 00:07:45,879 --> 00:07:49,240 flipping on Earth instantly makes the coin on Mars flip 160 00:07:49,279 --> 00:07:52,120 to the opposite side, doesn't that mean we can send 161 00:07:52,120 --> 00:07:54,959 a message across the universe faster than the speed of light. 162 00:07:55,240 --> 00:07:57,199 Speaker 2: It seems like we should be able to write. 163 00:07:57,279 --> 00:07:59,319 Speaker 1: Yeah, doesn't that break the ultimate speed limit? 164 00:07:59,399 --> 00:08:02,720 Speaker 2: It's such an question, but the universe has a very gentle, 165 00:08:03,120 --> 00:08:07,199 very strict way of protecting itself. It's called the no communication. 166 00:08:06,759 --> 00:08:09,040 Speaker 1: Theorem, Nature's gentle speed limit. 167 00:08:09,199 --> 00:08:13,800 Speaker 2: Exactly, while the connection the correlation is instantaneous, it cannot 168 00:08:13,800 --> 00:08:16,720 be used to transmit classical information faster than light. 169 00:08:16,959 --> 00:08:19,160 Speaker 1: But why not? If they're connected, why can't I just 170 00:08:19,199 --> 00:08:20,560 tap out a message. 171 00:08:20,160 --> 00:08:24,360 Speaker 2: Because of the randomness. Imagine two friends separated by light years, 172 00:08:24,439 --> 00:08:26,920 both rolling dice at the exact same moment. 173 00:08:27,000 --> 00:08:30,480 Speaker 1: Okay, they're sitting in the quiet dark just gently rolling 174 00:08:30,519 --> 00:08:31,120 a die. 175 00:08:31,240 --> 00:08:34,440 Speaker 2: Because of entanglement, they will always roll the exact same 176 00:08:34,519 --> 00:08:37,399 number at the same time. It's a beautiful mystery. 177 00:08:37,559 --> 00:08:39,559 Speaker 1: So if I roll a six, my friend light years 178 00:08:39,559 --> 00:08:40,559 away rolls a six. 179 00:08:41,159 --> 00:08:46,600 Speaker 2: Right. But here's the catch. Neither friend can force thede 180 00:08:46,840 --> 00:08:48,639 to land on a six. A. 181 00:08:50,440 --> 00:08:51,840 Speaker 1: I can't chose the outcome exactly. 182 00:08:51,879 --> 00:08:53,840 Speaker 2: The outcome is completely random, so you just get a 183 00:08:53,919 --> 00:08:56,720 random string of numbers. You can't use random numbers to 184 00:08:56,840 --> 00:09:00,960 spell out a secret message. You can't control the dance there. 185 00:09:00,840 --> 00:09:03,759 Speaker 1: But we can't weaponize it. We can't build a superluminal telegraph. 186 00:09:03,960 --> 00:09:06,679 Speaker 2: Nature protects the timeline of the universe, and there is 187 00:09:06,720 --> 00:09:09,519 another rule that helps with this, called the no cloning theorem. 188 00:09:09,720 --> 00:09:11,440 Speaker 1: The no cloning theorem tell me about that. 189 00:09:11,639 --> 00:09:15,240 Speaker 2: Imagine you were trying to perfectly trace a beautiful, intricate 190 00:09:15,320 --> 00:09:17,360 snowflake that just landed on your seat. 191 00:09:17,480 --> 00:09:18,799 Speaker 1: Oh they're so fragile. 192 00:09:18,919 --> 00:09:22,120 Speaker 2: The very moment your warm pencil touches it, the delicate 193 00:09:22,159 --> 00:09:26,240 ice structure melts and changes. You can never make an exact, 194 00:09:26,399 --> 00:09:29,360 perfect copy of a quantum state without destroying the. 195 00:09:29,279 --> 00:09:31,799 Speaker 1: Original, So if you try to copy the message to 196 00:09:31,799 --> 00:09:33,120 read it, it just melts. 197 00:09:33,120 --> 00:09:37,320 Speaker 2: Away, It just vanishes. The universe keeps its secrets perfectly safe. 198 00:09:37,559 --> 00:09:40,279 Speaker 1: It's so peaceful to think about the universe just quietly 199 00:09:40,399 --> 00:09:43,879 regulating itself, keeping the timeline secure. Yeah, but it makes 200 00:09:43,879 --> 00:09:46,960 me wonder. If the quantum world is this blurry, magical 201 00:09:47,000 --> 00:09:51,080 place of spinning coins and instant connections, why does everything 202 00:09:51,080 --> 00:09:52,600 around us feel so solid? 203 00:09:52,759 --> 00:09:55,159 Speaker 2: That is a wonderful question. How do we get from 204 00:09:55,279 --> 00:09:58,519 quantum magic to a solid chair or a warm cup 205 00:09:58,559 --> 00:09:58,919 of tea? 206 00:09:59,159 --> 00:10:01,639 Speaker 1: Right? Why is it my tea in a superposition of 207 00:10:01,639 --> 00:10:03,039 being both hot and cold. 208 00:10:03,399 --> 00:10:06,360 Speaker 2: It comes down to a process called decoherence. There is 209 00:10:06,399 --> 00:10:09,519 a very elegant recent paper from twenty twenty six by 210 00:10:09,559 --> 00:10:13,120 ex Wang that explores this. It describes how the quantum 211 00:10:13,159 --> 00:10:17,039 world gently transitions into the classical world we experience every day. 212 00:10:17,200 --> 00:10:19,240 Speaker 1: So how does it happen? How does the wave function collapse? 213 00:10:19,639 --> 00:10:23,240 Speaker 2: Imagine a delicate early morning fog. It's holding a million 214 00:10:23,360 --> 00:10:26,200 tiny droplets, just hovering softly in the cool air. 215 00:10:26,320 --> 00:10:28,000 Speaker 1: I can almost feel the dampness. 216 00:10:27,559 --> 00:10:31,000 Speaker 2: Of it, And slowly quietly, as the sun rises, that 217 00:10:31,080 --> 00:10:35,559 fog settles, it condenses into a single, perfectly clear drop 218 00:10:35,600 --> 00:10:37,919 of dew resting gently on a blade of grass. 219 00:10:38,000 --> 00:10:40,879 Speaker 1: That's the collapse, the fog becoming the solid drop. 220 00:10:41,120 --> 00:10:44,440 Speaker 2: Yes, and it doesn't happen instantaneously across the universe like 221 00:10:44,440 --> 00:10:47,840 a magical snap. It happens because of the environment. The 222 00:10:47,919 --> 00:10:49,519 environment gives it a soft. 223 00:10:49,200 --> 00:10:51,759 Speaker 1: Embrace, the soft embrace of the environment. What does that 224 00:10:51,840 --> 00:10:52,600 mean exactly? 225 00:10:52,720 --> 00:10:57,960 Speaker 2: Well, a quantum particle isn't alone. It's surrounded by stray light, gentle, warmth, air, 226 00:10:58,000 --> 00:11:01,480 molecules just drifting by. All these things constantly bump into 227 00:11:01,480 --> 00:11:03,279 the delicate quantum state. 228 00:11:03,240 --> 00:11:04,759 Speaker 1: Like little invisible taps. 229 00:11:04,919 --> 00:11:09,600 Speaker 2: Exactly. Imagine a spinning top. It's spinning perfectly, maintaining its balance, 230 00:11:09,759 --> 00:11:13,320 but it gets bumped by dozens of tiny invisible dust. 231 00:11:13,120 --> 00:11:15,080 Speaker 1: Motes floating in the sunlight. 232 00:11:14,759 --> 00:11:18,679 Speaker 2: Right, and those tiny bumps slowly sap its momentum until 233 00:11:18,679 --> 00:11:22,279 it softly, inevitably falls to rest on one specific side. 234 00:11:22,639 --> 00:11:24,120 We call these pointer states. 235 00:11:24,399 --> 00:11:26,480 Speaker 1: Yes, so all the warmth and light of the world 236 00:11:26,559 --> 00:11:30,159 just sort of gently nudges the quantum weirdness until it 237 00:11:30,240 --> 00:11:32,840 settles down into something normal and solid. 238 00:11:33,000 --> 00:11:38,360 Speaker 2: Yes, this local, continuous process suppresses the strangeness. It means 239 00:11:38,360 --> 00:11:41,279 that Schrodinger's famous cat, you know, the one in the box. 240 00:11:41,080 --> 00:11:43,720 Speaker 1: The one that's supposedly both asleep and awake. Right. 241 00:11:44,519 --> 00:11:47,600 Speaker 2: It resolves into a definite state long before we ever 242 00:11:47,639 --> 00:11:51,360 open the box, simply because the environment inside the box, 243 00:11:51,440 --> 00:11:54,600 the air, the heat of the cat itself, is already 244 00:11:54,600 --> 00:11:57,720 interacting with it. The environment is already looking at it. 245 00:11:57,720 --> 00:12:00,320 Speaker 1: It's so peaceful to think of the environment as a 246 00:12:00,480 --> 00:12:05,600 soft blanket, just settling all that quantum uncertainty into a calm, 247 00:12:05,960 --> 00:12:07,039 steady reality. 248 00:12:07,159 --> 00:12:10,200 Speaker 2: It really is. It's the universe wrapping us in stability. 249 00:12:10,679 --> 00:12:13,720 Speaker 1: But are there places where this quantum connection manages to 250 00:12:13,759 --> 00:12:17,039 survive in the big, warm world or does the blanket 251 00:12:17,080 --> 00:12:17,840 always smother it? 252 00:12:17,960 --> 00:12:20,399 Speaker 2: No, it survives, and we are starting to find it 253 00:12:20,480 --> 00:12:23,799 and even create it in larger, more complex systems for 254 00:12:23,960 --> 00:12:24,960 pushing the boundaries. 255 00:12:25,039 --> 00:12:28,080 Speaker 1: Pushing the boundaries like making big things entangled. 256 00:12:27,759 --> 00:12:31,759 Speaker 2: Yes, macroscopic things. For instance, scientists have managed to entangle 257 00:12:31,960 --> 00:12:34,440 tiny vibrating aluminum drumheads. 258 00:12:34,679 --> 00:12:36,559 Speaker 1: Drumheads like a musical. 259 00:12:36,159 --> 00:12:39,519 Speaker 2: Instrument, sort of. They are incredibly thin, about the thickness 260 00:12:39,519 --> 00:12:42,440 of a single strand of spider silk, and they breathe, 261 00:12:42,600 --> 00:12:43,679 they vibrate. 262 00:12:43,360 --> 00:12:45,240 Speaker 1: But they are big enough that you could see them with. 263 00:12:45,279 --> 00:12:49,200 Speaker 2: A standard magnifying glass. Yes, they are made of trillions 264 00:12:49,200 --> 00:12:53,000 of atoms, and scientists coax them into sharing a single 265 00:12:53,159 --> 00:12:53,919 quantum rhythm. 266 00:12:54,279 --> 00:12:58,159 Speaker 1: Trillions of atoms all dancing together in that perfect mirror image. 267 00:12:57,960 --> 00:13:01,240 Speaker 2: And they can maintain that delicate Wiet rhythm for up 268 00:13:01,320 --> 00:13:04,480 to half an hour in the quantum world. That is 269 00:13:04,480 --> 00:13:05,799 an eternity of peace. 270 00:13:06,039 --> 00:13:09,039 Speaker 1: Wow, half an hour just humming together. 271 00:13:09,279 --> 00:13:11,960 Speaker 2: And it's not just size. We're finding more complex ways 272 00:13:11,960 --> 00:13:15,360 they dance. There was a beautiful recent discovery out of. 273 00:13:15,320 --> 00:13:17,440 Speaker 1: The Technion a technion. What did they find? 274 00:13:17,799 --> 00:13:20,759 Speaker 2: They showed entanglement at the nanoscale, not just in the 275 00:13:20,799 --> 00:13:24,200 spin of a particle, but in its total angular momentum. 276 00:13:24,360 --> 00:13:26,799 Speaker 1: Total angular momentum. Can you paint a picture of that 277 00:13:26,840 --> 00:13:27,120 for me? 278 00:13:27,279 --> 00:13:30,279 Speaker 2: Imagine the Earth. It spins on its own axis, creating 279 00:13:30,279 --> 00:13:33,639 our gentle days and nights, but it is also simultaneously 280 00:13:33,679 --> 00:13:36,559 traveling along its vast long orbit around the Sun. 281 00:13:36,879 --> 00:13:39,200 Speaker 1: Right, two different types of motion, but they belong to. 282 00:13:39,200 --> 00:13:42,639 Speaker 2: The same planet exactly. The technian researchers found a way 283 00:13:42,679 --> 00:13:44,600 to bind both of those types of motion and a 284 00:13:44,600 --> 00:13:49,200 photon together into one elegant, inseparable dance, and then entangle 285 00:13:49,279 --> 00:13:51,639 that entire complex dance with another tarticle. 286 00:13:51,840 --> 00:13:54,679 Speaker 1: It's like choreographing a ballet for the universe. It's just 287 00:13:54,720 --> 00:13:59,519 incredible that this happens in sterile, quiet labs. But what 288 00:13:59,559 --> 00:14:03,480 about outside the lab? Could nature be using this hidden 289 00:14:03,519 --> 00:14:04,559 connection on its own? 290 00:14:04,960 --> 00:14:08,000 Speaker 2: That is where it gets truly magical. There are hints 291 00:14:08,039 --> 00:14:11,559 that biology itself is tapping into this deep quantum well. 292 00:14:11,759 --> 00:14:13,960 Speaker 1: Biology like plants and animals. 293 00:14:14,080 --> 00:14:16,240 Speaker 2: Yes, for example, in the leaves of trees as they 294 00:14:16,279 --> 00:14:18,279 breathe during photosynthesis. 295 00:14:18,360 --> 00:14:20,080 Speaker 1: So as I sit under a tree in the park, 296 00:14:21,080 --> 00:14:23,399 leaves above me might be using quantum mechanics. 297 00:14:23,559 --> 00:14:26,120 Speaker 2: It seems very likely when sunlight hits a leaf, the 298 00:14:26,279 --> 00:14:28,600 energy has to find its way deep into the plant 299 00:14:28,679 --> 00:14:31,960 cells to be used. It's a messy, chaotic journey, like. 300 00:14:31,919 --> 00:14:34,679 Speaker 1: Trying to walk through a dense, noisy forest exactly. 301 00:14:34,879 --> 00:14:38,240 Speaker 2: But Evan suggests the energy doesn't just stumble around. It 302 00:14:38,360 --> 00:14:42,919 enters a state of superposition. It gently explores multiple pathways 303 00:14:42,919 --> 00:14:46,159 at the exact same time, finding the absolute most efficient 304 00:14:46,240 --> 00:14:47,600 route and perfect harmony. 305 00:14:47,759 --> 00:14:49,519 Speaker 1: It's as if the life of the tree itself is 306 00:14:49,600 --> 00:14:53,120 quietly utilizing the deepest secrets of physics just to survive, 307 00:14:53,559 --> 00:14:55,399 just to turn sunlight into green leaves. 308 00:14:55,639 --> 00:14:58,879 Speaker 2: There are also hints of it in oral bionetworks. The 309 00:14:59,039 --> 00:15:04,639 tiny ecosystem bacteria. Life is incredibly resourceful. It embraces the 310 00:15:04,720 --> 00:15:05,519 quantum connection. 311 00:15:05,799 --> 00:15:07,960 Speaker 1: It really changes how you look at the natural world. 312 00:15:08,039 --> 00:15:10,279 It's all so much more connected. 313 00:15:09,840 --> 00:15:12,519 Speaker 2: Than it seems it is, and we are trying to 314 00:15:12,639 --> 00:15:16,159 learn from that. We are taking these delicate, invisible threads 315 00:15:16,279 --> 00:15:18,519 and trying to shape the future with them. 316 00:15:18,559 --> 00:15:20,240 Speaker 1: The quantum Internet, yes, a. 317 00:15:20,200 --> 00:15:23,399 Speaker 2: Whole new way of communicating built on the foundations of entanglement, 318 00:15:23,960 --> 00:15:26,960 and it relies on something called quantum teleportation. 319 00:15:27,240 --> 00:15:30,559 Speaker 1: Okay, teleportation. When I hear that, I instantly think of 320 00:15:30,600 --> 00:15:33,000 science fiction, you know, beaming people through. 321 00:15:32,799 --> 00:15:35,360 Speaker 2: Space, right, But it's much softer than that. We aren't 322 00:15:35,399 --> 00:15:37,799 beaming physical matter. We are moving information. 323 00:15:38,240 --> 00:15:39,000 Speaker 1: How does that look? 324 00:15:39,639 --> 00:15:42,759 Speaker 2: Imagine you have a deeply guarded secret recipe for a 325 00:15:42,799 --> 00:15:45,759 wonderful cake. You don't want to send the physical paper 326 00:15:46,120 --> 00:15:47,480 because someone might read it. 327 00:15:47,600 --> 00:15:49,279 Speaker 1: Okay, I have my secret recipe. 328 00:15:49,440 --> 00:15:51,879 Speaker 2: Instead, you whispered the essence of that recipe into the 329 00:15:51,879 --> 00:15:56,120 wind using an entangled connection, and instantly the exact same 330 00:15:56,200 --> 00:15:59,200 cake bakes itself in your friend's oven across the globe. 331 00:15:59,360 --> 00:16:01,720 Speaker 1: Oh wow, and my original cake. 332 00:16:01,799 --> 00:16:06,240 Speaker 2: Your original pake quietly vanishes. The information is perfectly transferred 333 00:16:06,240 --> 00:16:08,120 without ever crossing the space in between. 334 00:16:08,399 --> 00:16:11,559 Speaker 1: That is beautiful. But how do we protect that whispered 335 00:16:11,639 --> 00:16:14,799 secret from the environment, from the fog and the dust 336 00:16:14,799 --> 00:16:16,120 motes we talked about earlier. 337 00:16:16,159 --> 00:16:19,200 Speaker 2: We build something called decoherence free subspaces. 338 00:16:19,679 --> 00:16:23,840 Speaker 1: Decoherence free subspaces that sounds like a safe room. It is. 339 00:16:24,240 --> 00:16:28,720 Speaker 2: Imagine a quiet, perfectly still cocoon. Outside the cocoon, a 340 00:16:28,799 --> 00:16:34,080 chaotic storm is raging, wines, blowing everything around. But inside inside, 341 00:16:34,159 --> 00:16:39,279 a sleeping butterfly is perfectly protected. The subspace mathematically shields 342 00:16:39,320 --> 00:16:43,000 the delicate quantum information from the chaotic noise of the environment. 343 00:16:43,120 --> 00:16:45,600 Speaker 1: So we can send these entangled whispers across the world, 344 00:16:45,879 --> 00:16:47,519 completely safe in their little cocoons. 345 00:16:47,559 --> 00:16:50,080 Speaker 2: We are already doing it. The infrastructure is being built 346 00:16:50,080 --> 00:16:53,399 as we speak. There is a satellite called Mushous orbiting 347 00:16:53,480 --> 00:16:54,559 silently above us in. 348 00:16:54,519 --> 00:16:57,399 Speaker 1: The dark, beaming down entangled photons. 349 00:16:56,960 --> 00:16:59,799 Speaker 2: Yes, beaming them from the vacuum of space twelve hundred 350 00:16:59,799 --> 00:17:02,720 coss down to Earth. And we are weaving fiber optic 351 00:17:02,759 --> 00:17:05,720 networks right beneath our cities to carry these delicate connections. 352 00:17:06,000 --> 00:17:08,640 Speaker 1: It's like we're knitting a sweater of light around the globe. 353 00:17:08,920 --> 00:17:11,960 But what is the ultimate goal of all this. Is 354 00:17:12,000 --> 00:17:13,400 it just for faster communication. 355 00:17:13,599 --> 00:17:16,440 Speaker 2: Not faster No, the speed limit is still firmly in place. 356 00:17:16,519 --> 00:17:20,559 It's for absolute, unbreakable trust. It leads to concepts like 357 00:17:20,680 --> 00:17:21,359 quantum money. 358 00:17:21,599 --> 00:17:23,480 Speaker 1: Quantum money that sounds fascinating. 359 00:17:23,559 --> 00:17:26,680 Speaker 2: It is imagine money that is encoded in these fragile 360 00:17:26,720 --> 00:17:30,000 quantum states. If a bank wants to verify your money, 361 00:17:30,079 --> 00:17:33,319 they use entanglement to check it without ever looking directly 362 00:17:33,359 --> 00:17:34,400 at the funds. 363 00:17:34,000 --> 00:17:36,279 Speaker 1: Because if they look directly at it, it would melt like. 364 00:17:36,240 --> 00:17:39,720 Speaker 2: The snowflake exactly. Any attempt by a counterfeiter or a 365 00:17:39,759 --> 00:17:42,640 hacker to look at the money or copy it immediately 366 00:17:42,680 --> 00:17:46,559 destroys it. The very act of theft erases the prize. 367 00:17:46,640 --> 00:17:49,799 Speaker 1: So it's completely secure financial system. Yeah, not secured by 368 00:17:49,799 --> 00:17:53,079 difficult math, but secured by the fundamental laws of the universe. 369 00:17:53,240 --> 00:17:58,400 Speaker 2: It offers a decentralized, perfectly secure foundation, unhackable even by 370 00:17:58,440 --> 00:18:02,039 the most advanced computers of the future. The most abstract 371 00:18:02,079 --> 00:18:05,599 philosophical physics debate from a century ago is poised to 372 00:18:05,640 --> 00:18:07,599 become the bedrock of human trust. 373 00:18:07,759 --> 00:18:10,000 Speaker 1: And it's so humbling to think about. We've gone on 374 00:18:10,000 --> 00:18:12,680 such a quiet journey today. We really have, from just 375 00:18:12,720 --> 00:18:17,119 imagining those spinning silver coins of superposition, through the profound 376 00:18:17,160 --> 00:18:19,119 doubts of Albert Einstein. 377 00:18:18,680 --> 00:18:21,240 Speaker 2: To the scrap metal basement where John Klauser proved the 378 00:18:21,279 --> 00:18:22,559 magic was real, right, and. 379 00:18:22,519 --> 00:18:25,559 Speaker 1: Then looking at the macroscopic drumheads vibrating in the dark 380 00:18:25,880 --> 00:18:28,039 the leaves using quantum magic to drink the. 381 00:18:28,000 --> 00:18:30,480 Speaker 2: Sunlight, and finally looking up at a future where the 382 00:18:30,559 --> 00:18:34,799 night sky is filled with silent satellites whispering entangled secrets 383 00:18:34,880 --> 00:18:35,559 down to us. 384 00:18:35,839 --> 00:18:39,079 Speaker 1: It has been a beautiful exploration. But before we fade 385 00:18:39,119 --> 00:18:41,680 out completely, I know you have one final thought for 386 00:18:41,720 --> 00:18:44,440 our listener to gently drift to sleep on. 387 00:18:44,680 --> 00:18:48,079 Speaker 2: I do as you lie there, feeling the weight of 388 00:18:48,119 --> 00:18:51,440 your body settling into rest, think about this. If the 389 00:18:51,559 --> 00:18:56,000 universe is fundamentally woven together by these invisible, unbreakable threads 390 00:18:56,039 --> 00:18:58,720 of entanglement, and we know that we are built of 391 00:18:58,759 --> 00:19:01,160 the very same quantum us that was born in the 392 00:19:01,160 --> 00:19:04,519 fires of the early cosmos, every atom in you was 393 00:19:04,559 --> 00:19:06,440 once pressed together with everything else. 394 00:19:06,519 --> 00:19:07,319 Speaker 1: We were all connected. 395 00:19:07,640 --> 00:19:12,880 Speaker 2: Yes, So what unseen, delicate connections might you currently share 396 00:19:13,119 --> 00:19:16,200 right now with the furthest oldest stars in the night sky. 397 00:19:17,160 --> 00:19:19,720 You are never truly alone. You are woven into the 398 00:19:19,720 --> 00:19:20,680 fabric of it all. 399 00:19:20,640 --> 00:19:23,240 Speaker 1: Woven into the stars. That is a wonderful thought to 400 00:19:23,279 --> 00:19:24,880 carry into dreams. Thank you for this. 401 00:19:24,880 --> 00:19:28,519 Speaker 2: Time together, Wishing you a peaceful, deep and RESTful sleep. 402 00:19:28,599 --> 00:19:30,680 Speaker 1: Good night, Sleep well into the starry sky.
