Then he wants to demonstrate intercontinental quantum key distribution between stations in China and Austria, which will require holding one half of an entangled photon pair on board until the Austrian ground station appears within view of the satellite.

Many quantum encryption protocols work by measuring the «up» or «down» spins on pairs of entangled photons shared between a sender, conventionally called Alice, and a receiver called Bob.

To confirm that the particles were entangled, and that the weird qualities of quantum mechanics held, the researchers used the photon pairs to perform a Bell test (SN: 9/19/15, p. 12), which analyzes correlations between the two particles.

Physicists know how to create pairs of entangled photons, sub-atomic light particles, and have observed them operating in sync between two of the Canary Islands at a distance of 143 kilometers.

Although nearest - neighbour exchange coupling of two spins has been demonstrated, the interaction of spins via microwave - frequency photons could enable long - distance spin — spin coupling and connections between arbitrary pairs of qubits («all - to - all» connectivity) in a spin - based quantum processor.

No faster - than - light communication: The two detectors measured photons from the same pair a few hundreds of nanoseconds apart, finishing more than 40 nanoseconds before any light - speed communication could take place between the detectors.
