einstein proved wrong!!

First off, sorry for the click bait heading.

The heading is technically correct but does not imply what you think it means.

Einsteins theory of relativity still is true, e is always equal to mc squared and nothing can travel faster than the speed of light.But his views on quantum physics are highly controversial.His most famous argument was the EPR paper.The EPR paradox says If we have 2 quantum objects that can be described by a single wave function, then we can measure the velocity of one without affecting the other, and then know both the position and velocity of the other particle which contradicts the uncertainty principle.PR paradox says If we have 2 quantum objects that can be described by a single wave function, then we can measure the velocity of one without affecting the other, and then know both the position and velocity of the other particle which contradicts the uncertainty principle. Bohr tried to explain it by using quantum entanglement.but at that time, Einstein who thought everything could be explained by classical physics without the need of probabilities was skeptical and called it "spooky action at a distance".This spooky action at a distance has been achieved by scientists.The achievement is still a very, very long way from the movements familiar from science fiction, but strengthens our confidence in the theory of quantum entanglement, one of the most controversial aspects of modern physics. It may, moreover, assist the much closer goal of quantum computing.

Certain subatomic particles always exist in paired states. For example, two electrons may have opposite spins. This is fine initially, but creates a famous paradox if one particle is interfered with in such a way that its spin is changed. According to entanglement theory the other particle will instantly respond to the changes wrought on its pair so that the two remain opposite. 

However, the distance between the two this means that the information of what has happened to the one particle must be transmitted infinitely fast – faster than the speed of light.

n 1964 physicist John Stewart Bell came up with an idea for an experiment to test whether entanglement is real. At the time the test was impractical, but with publication in Science a team from the Delft University of Technology, Netherlands have got close to conducting Bell's test.

The Delft team trapped electrons in very low temperature diamonds, which team leader Ronald Hanson describes as “miniprisons”. This allowed them to measure the spin for each electron very reliably. Alterations to this spin were reflected in the spin of an entangled electron trapped in a similar diamond prison on the next bench.

The small distance between the two diamonds makes it hard to demonstrate that the transfer of information is occurring instantly, rather than at light speed. Consequently, the next step will be to entangle caged electrons and expand their separation across town or around the world. Entanglement between islands more than 100km apart has already been demonstrated, but only statistically, rather than with 100% success. 

Besides finally settling one of 20th Century physics greatest debates, reliable quantum teleportation could make possible the ultimate in secure communication channels, which would also be infinitely fast as well. Although this is starting to sound awfully close to Ursula Le Guin's ansible, most physicists dispute the possibility of such a device.

As usual, the result does not come out of nowhere. Other teams have also been able to teleport quantum information, but only in a minority of cases. Last year Hanson's team announced they had achieved quantum teleportation using diamond entrapment, but without the 100% reliability of the most recent work.
