Entanglement of single-atom quantum bits at a distance

Entanglement of single-atom quantum bits at a distance

The phenomenon of entanglement is a key concept in quantum information science. Atomic systems are promising candidates for quantum 'memories'. These in turn can be coupled and entangled by the exchange of photons, providing the basis of a quantum information processor. The signature of entanglement between remotely located atomic ensembles was recently demonstrated. Now Moehring et al. have achieved entanglement between two single-ion quantum m…

HRL Laboratories And Boeing Achieve Milestone In Quantum Entanglement Swapping Satellite Mission

HRL Laboratories and Boeing have completed construction and technical validation on a quantum communication subassembly for Boeing's Q4S satellite mission, marking a significant step toward demonstrating four-photon quantum entanglement swapping in space—a capability essential for secure communications and distributed quantum networks.
