Reconfigurable multi-mode entanglement within one beam

Armstrong, Seiji; Janousek, Jiri; Hage, Boris; Morizur, Jean Francois; Bachor, Hans; Lam, Ping Koy


New continuous variable quantum protocols such as cluster state computation [1] and quantum error correction [2] require an increasing number of modes to be entangled in a specific way. Conventionally, the entangled modes are carried by as many single mode beams [3, 4]. In order to produce entanglement, each beam of classical light first goes through a single mode optical parametric amplifier (OPA). This OPA reduces the variance of one of the quadratures of one mode of the electromagnetic field...[Show more]
