The material that quantum memories are made of: some international team of physicists has succeeded, in opposition to the first time, in storing a quantum mouth-piece in a diamond for longer than single second at room temperature. The researchers did not use a natural diamond like the unit shown here, however, neither was it divide. [...]

Quantum physicists be favored with constructed an elementary network for storing and exchanging quantum notice. The network was setup with two total-purpose nodes, which can send, suffer and store quantum information. The nodes were linked through . fiber-optic cable, which carries the quantum complaint from node to node with a pure photon. The prototype network [...]
