A high-brightness source of narrowband, identical-photon pairs.
We generated narrowband pairs of nearly identical photons at a rate of 5 x 10(4) pairs per second from a laser-cooled atomic ensemble inside an optical cavity. A two-photon interference experiment demonstrated that the photons could be made 90% indistinguishable, a key requirement for quantum information-processing protocols. Used as a conditional single-photon source, the system operated near ...
متن کاملRandom nonlinear layered structures as sources of photon pairs for quantum-information processing
Random nonlinear layered structures have been found to be a useful source of photon pairs with perfectly indistinguishable un-entangled photons emitted into a very narrow spectral range. Localization of the interacting optical fields typical for random structures gives relatively high photon-pair fluxes. Superposing photon-pair emission quantum paths at different emission angles, several kinds ...
متن کاملQuantum Microwave Radiation and its Interference Characterized by Correlation Function Measurements in Circuit Quantum Electrodynamics
Superconducting circuits provide an attractive architecture for quantum optics experiments in solid state systems. Microwave radiation interacts strongly with individual (macroscopic) quantum systems, and enables to realize emitters of single photons. The statistical property of emitting exactly a single photon as information carrier makes these emitters relevant for quantum communication and i...
متن کاملPhoton engineering for quantum information processing
We study distinguishing information in the context of quantum interference involving more than one parametric downconversion (PDC) source and in the context of polarization-entangled photon pairs based on PDC. We arrive at specific design criteria for two-photon sources so that when used as part of complex optical systems, such as photon-based quantum information processing schemes, distinguish...
