Oxford scientists say they’ve achieved quantum teleportation

YAHOO

Researchers at the University of Oxford say they’ve achieved quantum teleportation — stitching together separate quantum computers to run an algorithm collaboratively, across a distance, in a “breakthrough” they say could lead to powerful quantum supercomputers.

The scientists linked two quantum processors that were six and a half feet apart using a “photonic network interface,” as detailed in a paper published last week in the journal Nature.

The team, led by Oxford University Physics graduate student Dougal Main, hopes the achievement will lay the groundwork for a “quantum internet” of distributed ultra-secure processors.

It’s not technically the first time scientists have demonstrated quantum teleportation. Previous research has shown that the states of quantum bits known as qubits — the equivalent of a conventional computer’s bits, except they can be superimposed and entangled — can be transferred across physically separated systems.
