Physicists build first single-photon router

(PhysOrg.com) — By demonstrating that an artificial atom embedded in a transmission line can route a single photon from an input port to one of two output ports, physicists have built the first router working at the single-photon level. The single-photon router could one day serve as a quantum node in a quantum information network, in which it could provide basic processing and routing of data.
