Scientists Achieve Teleportation Between Earth and Orbit

Bright Side

Teleportation isn’t just sci-fi anymore — scientists have actually pulled it off between Earth and orbit! They didn’t teleport people (yet!), but they managed to instantly send quantum information from the ground up to a satellite. It’s called quantum teleportation, and it’s a huge step for future tech like super-secure communication and maybe even crazy stuff we haven’t dreamed of yet. The experiment shows that it’s possible to connect places across massive distances almost instantly. It sounds like something straight out of a movie, but it’s happening right now. Space just got a whole lot cooler!

00:00In 2017, Chinese scientists achieved what seemed impossible. They managed to teleport

00:06a light particle. And not just by a few inches, but from Earth up to their space satellite,

00:12which is 310 miles away. Now, teleporting a photon might not sound impressive to you,

00:18you buzzkill. But it was a historic moment for quantum mechanics and space technology.

00:24Sure, we're not zapping people back and forth like in Star Trek yet, but it's the first step.

00:31The satellite, which is a celebrity now, is named Myseus. It's equipped with special tech to receive

00:37and read the quantum state of the teleported particle. Myseus is the first place in the

00:42universe with which our planet has a quantum lane. So, what's next?

00:48The experiment had to be conducted in a super-controlled environment,

00:52in full peace and silence. So, no wonder they decided to do it in Tibet.

00:58A ground station in Negeri is located over two and a half miles above sea level,

01:04about half of Mount Everest's height. At such heights, the air is noticeably clear,

01:09and not even the tiniest dust particle can mess the teleportation up.

01:14This teleportation technology is based on extraordinarily complex theories,

01:19including ideas of Stephen Hawking. And the main trick here is that it's not traditional

01:24teleportation. Not in a sense we're used to. Everything there works on a funky concept

01:30called quantum entanglement. Basically, it says that two particles, like photons in our example,

01:37can be linked together in such a way that if you change something about one,

01:42the other one changes instantly, no matter how far apart they are. Even if there's an entire universe

01:48between them, they'll still feel the changes in each other right away.

01:53And that's not the creepiest part. All electrons, photons, atoms have their own quantum state,

02:01which describes all the information about them. Stuff like their properties, position, and energy.

02:06Scientists can read this information getting to know the particle. And for some crazy, unexplainable

02:12reason, as soon as we learn information about one entangled particle, the other one becomes its copy.

02:19Imagine there's a brother and sister who live in different towns. But when you get to know the

02:24brother, the sister suddenly becomes his twin. Weird analogy, but you get the idea.

02:30Nothing traveled between these particles. They didn't exchange any information with each other.

02:35They just know that we know. It's like they have a strange, invisible bond that nothing can break.

02:42This really unnerved Albert Einstein back in the day, since he believed that nothing can travel

02:47faster than the speed of light. But this communication happened faster. Einstein called this

02:53a spooky action at a distance. In any case, here's how the Chinese scientists pulled off their experiment.

03:00First, they entangled, or linked, some pairs of these photons in a lab on Earth. They kept one photon of

03:08each pair on the ground and transmitted the other one up to Mysias using a high-precision optical system,

03:14and equipment on the satellite caught it. After that, they read info about both photons,

03:20the one on Earth and the one in space. And, you guessed it, the ones in space copied the information about

03:27their buddies right away. So, by reading info about a particle at spot A, we can transfer its state to

03:35spot B through that invisible quantum link. Which means that actual real-life teleportation is not

03:42about literally moving you from Earth to space, but about creating a full quantum copy of you somewhere

03:49else. Now, isn't that insane? It's actually quite horrifying and opens up a lot of questions.

03:56So, imagine you have a famous old ship. It's so cherished that, over time, as parts of it wear out,

04:03each piece is replaced with a brand new one – an exact copy of the original. After many years,

04:09every single part and nail of the ship has been replaced by their identical copy. Now, the fun

04:15question pops up. Is this shiny ship still the one you had? Or is it something entirely new?

04:22That's a famous philosophical riddle called the Ship of Theseus. You can see how we ask the same

04:28about people and photons. So, let's take this Chinese technology and teleport you from Earth to Mars.

04:35Every part of you, every particle, is recreated perfectly on Mars based on the quantum information

04:42sent through space. Are you on Mars still you? That's a tricky one. Both versions would feel

04:50like the real you to themselves. So, here are some possible options.

04:55Option 1. Nope, that's not you. Because we only transferred information about you,

05:00and not your literal physical atoms that you're made up of. The original ship was always the real one,

05:06because its particles never changed. Now, on the other hand, okay, maybe the atoms are different,

05:12but this person literally thinks like you and remembers everything that you remember. From a

05:18quantum perspective, if you guys have the same quantum information, you are literally indistinguishable.

05:25So, both ships are the real ones. And the final option is that it's not just about atoms or

05:31consciousness, but about your life experience. You're still in the lab talking to scientists,

05:37while the other one is now enjoying the Martian sunset. No matter how similar you are, it's your

05:43history in life that makes you, you. Was that some kind of crazy philosophical puzzle?

05:51But let's get back to reality. How can this teleportation change our lives?

05:56One of the coolest things will be the quantum internet that spans our entire planet.

06:01The internet is basically a superhighway, where information zips back and forth like cars.

06:07But it still takes some time for light particles to travel from their servers to your phone or PC.

06:14Now, imagine a world where all this data appears on your device instantly,

06:18and all computers work much, much faster than they do now. Plus, all communication would be super secure.

06:26After Chinese scientists made this discovery, things have been progressing crazy fast,

06:31in the world of quantum mechanics. Just this year, scientists achieved another huge feat.

06:37They managed to teleport quantum states with nearly 90% accuracy, even in noisy conditions.

06:44Remember how we said that Tibet was the perfect place for our experiment? That's because there's

06:48no greater enemy for quantum teleportation than noise. The entanglement is a very delicate thing,

06:55more fragile than houseplants. Literally anything from the outside can easily disturb it and destroy it.

07:02Before, scientists tried their best to teleport stuff in noisy conditions. They designed special

07:08paths for the light to travel, and used some cool gadgets to keep the light particles stable and not

07:14get all fuzzy and mixed up. But now, they went a step further. They made a cool machine that helps

07:20particles avoid the noise. Even though there are still disturbances around, like bumps and stuff,

07:26the magic machine made sure that the connection between the photons stayed strong and the teleportation

07:33worked properly. So now this teleportation almost always works.

07:38Another cool experiment was conducted in Germany. They found a way to send quantum information through

07:44our regular internet, the ones you used to watch this video. Hooking the quantum internet up to the

07:50regular one is tricky, because they work differently. Remember what we said about noise?

07:55Well, this would be like trying to have a very delicate private chat in the middle of a noisy party

08:01without anyone else hearing it. All the regular internet noise usually breaks quantum information

08:07instantly. Which is why, usually, it needed a quantum link, its own quiet road. But the German

08:14scientists wanted to see if they could somehow send quantum information along with regular internet

08:20data down the same road. So they used this cool technique where they gave quantum and regular data

08:27a special rhythm so they don't bump into each other along the way. And that's how they managed to send

08:33quantum states through our regular optical fiber, the internet's main road. Nothing got mixed up,

08:40and things are still super secure. Now we just need to find a way to make this work on very big distances,

08:46and the online world will be faster and safer. Quantum internet! We're all waiting for you!

08:53Maybe then I'll be able to watch YouTube normally when someone downloads stuff in the other room.
