Delft QuTech lab entwines about 1.3 kilometers – update




Scientists at TU Delft seem conclusively demonstrated that quantum teleportation of information works. The researchers knew quantum information to entwine about 1.3 kilometers on the university campus.

The researchers have to test to see the strangest feature of quantum theory exists, that information can be teleported over a distance. By teleportation information does not move between two points, but the transfer will take place through the entanglement of the properties of these particles. Changes also have immediately without any time in between, affects the other particle. Because these properties go against the idea that nothing can travel faster than light, Einstein suspected that there were hidden variables exist. Which now seem to really exist. It is not a question to teleport physical objects, but information.

Because there is no transmission of information between the particles occurs, teleportation is the future dreamed for safely transmitting messages, just because nothing is sent. Nothing can be intercepted, because there is nothing to intercept. The property was already demonstrated for a longer time, but there was still a doubt.

The experiment is based on the fact that a particle in different states can exist: a superposition. The qubit, the quantum bit for computers, can at one moment both zero and one. A particle can spin in both directions at the same time. The difficulty of carrying out measurements in quantum physics experiments, is that measure alone exerts a direct influence on the particle to be measured. The coherent superposition disappears in perception.
