Important note: this is about quantum teleportation. They transferred data between two quantum computers without a cable or wifi. Teleporting matter, let alone matter in useful quantities is far off.

So what is being teleported? The state of the two entangled particles?
This highlights the problem with using that term. The two particles assume a state at the same time at a distance. It has 0% to do with the colloquial term.
So, Bluetooth?
nah, bluetooth and wifi both use electromagnetic radiation. I didn’t read the article and I understand nothing about quantum mechanics, but I don’t think they use photons in this. someone correct me if I’m wrong.
They used a fiber optic cable which transmits information using photons.
Bluetooth ain’t faster than the speed of light
It is, in fact, significantly slower, when it works at all.
This is not correct. Bluetooth is a radio frequency communication tool. RF is part of the electromagnetic spectrum and does, in fact, "move’ at the speed of light.
What @knightly@pawb.social said, but I do appreciate the lesson!
Yes, I got really excited, wondering if they’d solved reassembly.
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 adequately describe a qubit you shouldn’t even care about this.
The actual paper is beyond my level of physics knowledge, but Oxford uni published an article about it themselves which looks far better to me. No clickbait headline and it explains the significance of the achievement far better
First distributed quantum algorithm brings quantum supercomputers closer
Great article, thank you for sharing
So not FTL right?
I assume not, but primarily because I would expect the actual scientists and/or Oxford to make a bigger deal out of that if they had achieved it
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.
Edit:
I’ll need more sleep before attempting to read let alone understand the published paper. No promises in how long it’ll take for me to provide my thoughts on it.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.

Where’s it say they used a laser to transfer the information? This sounded like quantum entanglement was being demonstrated here

The word laser does not appear once in this article.

So…not in the article, but in a completely different linked article. Got it

Hyperlink which went to a different article. Do you not understand how the Internet works? Don’t act like you weren’t wrong when you failed to clarify properly. That’s not on me
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…?

ah, ok that is interesting, thanks!
One step closer to beating the homophobia that is distance :3
