Look, as someone that’s not afraid to be wrong I’m gonna say that I’m skeptical and say that I don’t trust this is real until I’ve read the research papers.
Reading the news nowadays kinda feels like “trust me bro” unless there are several additional systems based on logic that corroborates what is said as truth.
Couldn’t agree more. At first when I read it, I was like “wow”, the my logical brain did a re-read and I was like “doubt”.
This isn’t a first, quantum teleportation has been a thing since 1997. The breakthrough here is teleporting the information of an entire logical gate. The usecase here enables them to link multiple smaller quantum processors together so they can act as one bigger system.
It’s real, but the jargon is unintuitive.
“Teleportation” in the field of quantum mechanics refers to the process by which a quantum state can be copied from one place to another.
This process is like Shrodinger’s Cat, both alive and dead until you open the box to check. Quantum information simply does not exist until a measurement collapses it into back into classical information.
Can someone explain how using lasers to transmit an image means it was “teleported”?
Think of it like an identical pair of Shrodinger’s Cats. You can’t know if the cat is alive or dead 'til you open the box, but because they’re identical you know that the other box will show the same result as your own.
The lasers don’t transmit information, they transmit quantum randomness. The act of measuring this randomness creates information, and because the photons are entangled this information includes what was received at both ends.
So the photons that carry the information aren’t teleported, but the information itself is because it doesn’t exist until it is observed.
That sounds like complete garbage though, if those qbits are still in superposition then it hasn’t changed from being both 1 and 0. All that means is that nothing has really between the two points and the teleportation is theoretical.
Where’s it say they used a laser to transfer the information? This sounded like quantum entanglement was being demonstrated here
One step closer to beating the homophobia that is distance :3
Nah, this technique is more like having a Shrodinger’s Cat that’s in two places at once. It won’t collapse the tyrrany of space, but it will allow us to build bigger and better quantum computers.
Oki :3
Can someone explain the significance of quantum teleportation in qbit architectures?
From what little I understand, it relies on quantum entanglement instead of electrical current to ‘pass’ logic states between qbits in different physical space, but I’m wondering why (in this case) they still need to be connected by fiber optic cables?
I thought the point was that it didn’t need to pass signals over physical media, and that was valuable because it was instantaneous and secure, but now it’s sounding more like conventional computing…?

Clickbait and a borderline-lie.
Quantum teleportation is a very technical thing you can do with qubits, no actual matter is moved. If you can’t describe a qubit you shouldn’t care about this.
