Quantum Entangled Computer Memory Over 30 Miles Enables Quantum Internet | NextBigFuture.com

Chinese scientists have transmitted quantum computer memory between two entangled clouds of atoms over 50 kilometers. They developed an efficient atom-photon entanglement source that is suitable for low-loss transmission in fibers. This means a quantum internet could span a large city network. They entangled two clouds of a billion atoms then extracted a photon from each cloud. A quantum internet that connects remote quantum processors should enable a number of revolutionary applications such as distributed quantum computing. Its realization will rely on entanglement of remote quantum memories over long distances. Despite enormous progress, at present the maximal physical separation achieved
