Abstract
Methods and apparatus for long-distance quantum communication and scalable quantum computation are disclosed. The methods and apparatus are based on probabilistic ion-photon mapping. Scalable quantum computation is achieved by forming deterministic quantum gates between remotely located trapped ions by detecting spontaneously emitted photons, accompanied by local Coulomb interaction between neighboring ions. Long-distance quantum communication and scalable quantum communication networks formed by employing a number of remote nodes that each include an ion trap and by employing probabilistic photon-mediated entanglement between the ions in each ion trap.
