Passively stabilized single-photon interferometer
文献摘要：
A single-photon interferometer is a fundamental element in quantum information science.In most previously reported works,single-photon interferometers use an active feedback locking system to stabilize the relative phase between two arms of the interferometer.Here,we use a pair of beam displacers to construct a passively stable single-photon interferometer.The relative phase stabilization between the two arms is achieved by stabilizing the temperature of the beam displacers.A purely polarized single-photon-level pulse is directed into the interferometer input port.By analyzing and measuring the polarization states of the single-photon pulse at the output port,the achieved polarization fidelity of the interferometer is about 99.1±0.1％.Our passively stabilized single-photon interferometer provides a key element for generating high-fidelity entanglement between a photon and atomic memory.
