Oxford scientists have achieved something mind-bending: they successfully "teleported" information between two quantum computers located two meters apart.

This isn't Star Trek-style teleportation of objects(yet), but rather the instant transfer of quantum information using light particles.

Think of it like a super-advanced game of catch, where two quantum computers toss information back and forth without physically connecting.

The team managed to do this with 86% accuracy and even used it to run a special search algorithm.

Why does this matter?

Just like the internet connects regular computers to make them more powerful, this breakthrough could lead to a "quantum internet" that's exponentially faster and more secure than anything we have today.

That's such a superficial example. This has implications for literally everything we thought we knew about the nature of space and time.

Anyone who has read Timeline by Crichton knows why this is a bad idea for a person: transcription error.

Someone help me out here on what Im missing. How is this "ground breaking"? 2 meters to transfer information? My wifi goes farther than that

Just what we need... the ability to access and exchange info with devices without a connection.

I believe quantum information refers to to particle pairs that are dependent on each other. So if you can observe one particular you know what the other is doing whether they are 2 meters apart or 2 light years apart. All other communication speed is limited by the speed of light.

My understanding is the information isn't transferred, it exists simultaneously in both places.

One of the more esoteric interpretations of this is support for the hypothesis that consciousness exists outside the brain, thus offering a scientific rationale for life after death.

They didn't explain the mechanism by which the information travels and leads someone to the "my wifi does that" above. I assume it is quantum entanglement (spooky action at a distance). In any case the word "instant" bears specificity because if it is truly "instant" then we are breaking a speed limit we don't know a lot about. We think of a light coming on instantly when we flip a switch but in one respect it doesn't. Even setting aside the time it takes to produce photons from the time current hits the light the speed the "signal" moves through the wires is only about 90% the speed of light. If it is truly instant and thus going faster than the speed of light that is a massive result.

If this is repeatable then it would likely feed Moore's law for another generation.

Also, if it just copies information, wouldn't there be two of you at that point? If the original disappears, does that mean they are dead?

That's not what's happening though. Transfer of a quantum signal must always be accompanied by a classical signal - in other words a classical signal to effectuate transmission of the quantum signal. Neither alone will make the process work.

Therefore, the package as a whole cannot, as one would suspect, exceed the speed of light, which remains to our knowledge absolute.

Interestingly, the sender need not know where the receiver is located because the focus of the transmission results from paired particle entanglement rather than a directed signal.

Completion of the transmission does not give information from the receiver unless the receiver replies with their own signal.
