Delft University scientists 'teleport' information over three meters

Friday 30 May 2014

Scientists at Delft University are claiming to have managed to ‘teleport’ information over a space of three meters, according to a report in scientific journal Science.

The researchers say computers were able to exchange information despite not being connected to each other in any way. In addition, information did not travel across the three meter space between them, broadcaster NOS reports on Friday.

In order to transport the information, the researchers used a phenomenon known as ‘entanglement’, which researcher Ronald Hanson describe as ‘possibly the weirdest and most intriguing consequence of the laws of quantum mechanics.’

The information which was transferred was stored on diamond quantum bits, which could eventually be used for developing quantum computers and quantum Internet. The advantage of such a network is that information can be sent in total security and there is no way of eavesdropping.

The researchers plan to try to repeat the experiment this summer using a distance of 1,300 meters. However, NOS points out, the teleportation of objects such as people, remains impossible according to the laws of science.

Personally I'm certainly not qualified to wage any comments on this one but I got the distinct impression this is considered to be a major breakthrough.

EDIT: simplified one link

I remember seeing something about this about a year ago. If im not mistaken it is not the exact same particle, but they imprint another particle with the signature of the original making them virtually identicle. As i remember it it is a first step to teleportation.

This is just my brain rambling on, but they're calling it quantum communication but could it not be two particles linked by a gravity wave?

If light is a transverse wave function (a relatively slow one at that, only 300,000m/s) and gravity is a longitudinal wave function that's billions of times faster, it's possible there's some kind of neutrino connection between these two particles that happens so fast they simply can't measure it.

That said, how the heck would they measure a neutrino/gravity interaction anyways!? Clearly we don't have the technology to do it, but perhaps this is a tiny first step. (I think Wal Thornhill over at Thunderbolts is onto something here, and surprisingly former comic book artist Neal Adams has a theory that's right up the same alley.)

Imagine instantaneous communications anywhere in the solar system, and only 1/2 second delays to talk to someone on the other side of the galaxy.

Cool. Assuming our society survives the comet/nuclear war/Draconian harvest that is.
