Researchers Smash Quantum Teleportation Distance Record, Beaming a Photon Over 89 Miles

Can they point this thing towards our government to solve our problems; the bunch of dimwits!!! They could use brightening up in solutions and less vague proposal magic tricks! I WANT SOLUTIONS that are clearly defined too!

Distance is one thing, I cant wait to see more quantity of material vs a single proton. Hurry up and find the solutions for quantum computing.

The government is not interested in solving problems. They're only interested in stealing money and 'appearing to do things' that they perceive will appease voters in order to get re-elected so they can continue to steal money.

You have clearly stated the facts correctly! Your proton sir burns ever so bright between your two ears!

Proton or Photon? Anyway, I hope that's a good thing :)

Sorry I said Proton instead of Photon 1st and I believe it went viral.

I mean really who transports light? haha

This will become impressive when they stop teleporting photons and start teleporting something physical... like a grain of sand.

It seems to me we have the concept fully developed in terms of teleporting information. What everybody is hopeful of and waiting on is physical matter to be beamed across some great distance. So we need to begin work on how to measure the quatum state of however many atoms are in a grain of sand, do so very quickly, store that data, transmit it, decode it, and input those quantum measurements into a "cloud" of "quasi-matter" that could be anything we tell it to be.

Can we get some real research going on here instead of the same old project done over and over again. This is like going to a science fair and seeing yet another... volcano!

Come to think of it, there is some physicist who settled the debate between Einstein and Neils. The big question was whether or not quantum states are predetermined or random. I can't think of the guy's name but he postulated that if you could measure many quantum states you could find that out, he built a machine to do so, and determined that quantum states are indeed random. That was over 40 years ago, maybe improving on that machine might allow us to take the quantum state of every atom in a grain of sand in a second or so. With our advances in lasers, "imprinting" quantum states on a cloud of random base matter might allow us to "build/transport" that information on the other end.

That sounds more like duplicating something rather than transporting it. Which would have some great uses in itself, as in once you have the 'blueprint' and the raw material, you could theoretically make anything.

The real trick would be transporting a living thing, and how does the individual get transported.

Sorry Bob, thats how quantum teleportation (QT) works. The original object isn't physically transported from location A to B. It actually takes 3 photons: A, B, and C.

A and B are entangled...

You have B, I have A.

I also have C, which is the one I want to "teleport" to you.

I measure A and C, which gives me information on them. But note that in quantum operations, the very act of measuring them will destroy them. But in doing so I gained 2 pieces of information, one piece on each photon...

At this point, your photon (B) has information on the measurement I just took but it is a cloud of possibilities really, it could be any of 4 states.

I provide you information on the measurements I took on AC, you do a little work and boom, your photon (B) settles into a quantum state identical to C. So on the quantum level, its identical in every way to my C... but bear in mind that when I measure C I destroyed it.

Like I said, we need to start doing this with real matter, not just photons.

To transport a living thing we'd need to go through the process I outlined earlier in very little time, I'm talking attoseconds... imagine if your heart tries to beat when its only half complete... won't work out well for you. So we need to start out with non-lving physical matter, start small, work our way up in speed and complexity.

Well why would anyone want that?! It would be no better than cloning yourself. Even if it is an exact copy of you that thinks (along with everyone else) that it is you, YOU still died in the process. I, personally, wouldn't want for me and my subsequent copies to have to die every time I felt like teleporting to the grocery store.

"...A photon is an elementary particle, the quantum of light and all other forms of electromagnetic radiation, and the force carrier for the electromagnetic force, even when static via virtual photons..."

Agreed you would still die. What we'll need to do in order to make the teleportation work as lawsonrw states. Is to find some way of transferring your consciousness perhaps into a computer system then since the body cannot live without the mind body is destroyed new one created in exact detail consciousness transfer to new body transportation successful without possibility of death to consciousness. Although we would all rather the material from A transfer directly to B without the need for C.

This will upset everyone, but I actually know 8 people who have been teleported (successfully) over a distance, in some cases 1000's of km.

3 or 4 of them are my personal friends.

How?

God actually transported them supernaturally, so teleportation is actually occurring now.

lawsonrw - Thanks for the explanation.

"Like I said, we need to start doing this with real matter, not just photons."

-Which is why I made a note in another comment -photon or proton?, knowing we are talking about photons.

Yea, I have no idea even with imagination turned to maximum gain how a physical atom would be turned into a series of electrons or photons, beamed somewhere and returned to the same physical atom at the destination.

Sending the 'information' seems a lot more plausible, but then were down to talking about duplication through the reconfiguration of matter and not transport. Like a 3D printer but with a lot more capability.

2134 - The Airlines today announced a 400 dollar service fee to teletransport any baggage beyond a simple carry-on.

89 miles is impessive, too far to be along a line of sight. (A laser beam can go a long way, if not obstructed.) So an amateur would wonder how did they know this as the same photon that left the point of origin, and how did the photons become entangled in the first place, and how was the target photon transported to the destination point? And then, how did they know the travelling photon had arrived? Enquiring minds want to know.

Excellent questions, genedoug.

Any answers?
