Research team claims to have accurately 'teleported' quantum information ten feet

(Phys.org) —A team of researchers at Delft University in the Netherlands is reporting in a paper they have had published in the journal Science, that they have successfully used entanglement as a means of communication, over a distance of ten feet (three meters). Furthermore, they note, they did so with 100 percent reliability and without altering the spin state of the quantum bits (qubits) involved.

Teleportation, is of course, a means of moving an object from one place to another without it having to travel between them. Thus far examples of it have only been seen in science fiction movies. The idea of moving information in similar fashion, however, has met with some, albeit limited success. The idea is to use the concept of entanglement of particles as a means of conveyance. It's supposed to work because of the strange interconnectedness of the two particles—whatever happens to one, automatically happens to the other, regardless of the distance between them. Such a property should allow then, for the exchange of information. If the of one qubit is altered, then it should be automatically altered in the other qubit—a form of information exchange which can be counted as a message of sorts if a string of such transactions can be carried out.

To date, scientists have struggled to use entanglement as a means of communication—it's been achieved but the error rate has been so great that it would be unfeasible as a real-world application. In this new effort, the researchers claim to have solved the error rate problem—they've brought it down to zero percent. They did it, they report, by trapping electrons in diamonds at very low temperatures and shooting them with lasers, resulting in the creation of . The diamonds, the team reports, serve as really tiny prisons, holding the electrons in place. Held as they were, the researchers were able to cause a spin state to exist and then to read it at both locations, which meant that information had been conveyed.

The research team next plans to extend the distance between the qubits to 1,300 meters, while others presumably will attempt to replicate the first result—if the claims prove true, the breakthrough could mark the first stage of a the development of a true quantum computer, or network.

ABSTRACT
Realizing robust quantum information transfer between long-lived qubit registers is a key challenge for quantum information science and technology. Here, we demonstrate unconditional teleportation of arbitrary quantum states between diamond spin qubits separated by 3 m. We prepare the teleporter through photon-mediated heralded entanglement between two distant electron spins and subsequently encode the source qubit in a single nuclear spin. By realizing a fully deterministic Bell-state measurement combined with real-time feed-forward quantum teleportation is achieved upon each attempt with an average state fidelity exceeding the classical limit. These results establish diamond spin qubits as a prime candidate for the realization of quantum networks for quantum communication and network-based quantum computing.

So, now that our sun is a monopole, exuding tremendous energy not available when our sun is a dipole, we discover our 'alternate' universe.
Certainly explains how we can have 'cold fusion' and not be able to repeat it. Sun flakes of shed energy --from the monopole phase--impact Earth vicariously. One wonders if this discovery is yet another repeat of ancient known science. Science hopes to site a satellite at the edge of our magnetosphere to redirect energy to Earth to recreate the energy volume of our sun's monopole phase.

Teleported is a nonsensical explanation for speeds of transmission at a sub atomic level that we cannot measure or maybe even as of yet comprehend.
Has there been any reason to believe the distance (between 2 entangled particles in different galaxies) is zero?

More likely the speed is such at that level that information can travel faster than we can measure meaning 1 the speed of light is only a limit above the atomic level and 2 general relativity is wrong if the speed of light can be surpassed.

Can someone please clarify this for me? Assuming that the research team's experiment can be replicated and that they are successful in using entanglement to communicate information reliably for much longer distances, does this mean that information can be communicated faster than the speed of light - opening the door to communication with other intelligent life at vast distances in short intervals rather than over millions of years?

Since we're talking about entanglement, does this mean they transferred information faster than the speed of light?

Sorry Cosmo, didn't see you'd already asked the question.

I can answer one part of your question however. Even if we can convey information faster than light we still can't communicate with alien races we've never had physical contact with. There would be no other way to entangle the particles in order TO communicate with them. Essentially we'd be on different networks with no way to "link" them other than meeting in person and exchanging particles....

For all the Big Bang believers, something to think about.

If nothing is faster than the speed of light.

How did many galaxies come to exist in minutes.

The speed limit only applies to information traveling through space, not to space itself

Bingo! "the speed of light is only a limit above the atomic level". Right on the money. "visible light", that is.
The rest is not right.

It would be nice if entanglement can be used for communication. One such application that I can think of would be to use it aboard space probes/rovers. However I'm uncertain that the kind of communication they are talking about here, is of this nature.

they didn't even mention whether or not they maintained entanglement after information transfer. which isn't to say I believe it's impossible, but I do think they're a little hopeful. Not in the energy levels they're talking about.

yeah- it's all well and good that you can demonstrate the phenominon of entanglement, but this is not the first step towards transfering information unless you want to have 2-5 entangled particles per bit you're attempting to send.

not to mention the build proccess, the fact the miniprisons can't be heated or travel over a certain speed...

So much is at stake here; It is highly Stupid to aspire for Human Teleportation right away because of the Safety issues inherent in that aspect.
Most important is to be able to Teleport the Entire house OR even Car/Truck/Steamer/Airplane/Spaceship/Satellites for that matter! Imagine the Amount of Fuel that can be saved & the ease & swiftness with which EVERYTHING will be within our reach; As Chinese make stuff, they are in our backyard, WoW! We can move & work in the town/country of our choice. We can beat Jesus in that.
So, it is highly imperative for Walmart & Amazon to Check the Genuinity of this finding ASAP...to make sure there is no Obokata-type Deep Trap is involved... and keep on Investing more & more in this Research as more & more positive results are obtained! All The Best to WE the PEOPLE again ASAP.

They don't say the transfer is instantaneous or FTL, only that they believe this occurs without travelling through the intervening space. Perhaps when they can turn off the interconnecting laser or separate the devices with a solid concrete wall then they might be onto something. Presently it's nothing more than a trick of the light. Another case of publish or perish?

THIS IS HUGE!... the focus in this field should be to create ASAP a pair of communicating particles and make one permanently fixed in a laboratory to live hundreds or thousands of years ... and then the other pair to be easily and perpetually movable in a stable manner than can survive hundreds and or thousands of years in its movable container (or ship).

The moment those two particles are created in our time we should expect to be hearing from people in the future who can then use the movable particle to communicate back in time to the stationary particle.

We should hear from someone almost immediately after the two conditions are created. If not then it means that something went wrong with the apparatus in the near future before anyone could send a message back in time.

it is impossible for our time to go back in time, but if the apparatus is built then future people can communicate back to the time when the apparatus they can use was built.

What I'm curious about is what the experiment on entanglement in a changing gravity field will do. If it behaves as predicted, we may then end up with the predicament of being able to establish an entangled pair as per this experiment, but have difficulty in keeping them entangled over long periods of time due to changing strengths of gravity and velocity. Simply altering the elevation of one of the particles would be enough to spur disentanglement.

yes but it would not matter to us in our timeline.

no paradox would be created if they send info to us that cause them to not exist a millisecond after they hit send.

there would still be a working device existing in the future that can communicate with us in our present. should not be hard then to do binary code and hook us up to the internet of 100 or 1000 years into the future.
