Abstract

Optical quantum networking protocols impose stringent requirements on the states produced by sources of entanglement. We demonstrate a free-space, compact, source of indistinguishable pairs of polarization entangled photons, with an integrated local oscillator reference as a significant step towards this goal. This source achieves \(99.11 pm 0.01\)\% polarization entanglement visibility, \(96.3 pm 0.6\)\% successive-photon Hong-Ou-Mandel interference visibility, \(68.0 pm 0.1\)\% heralded efficiency as detected, and \(88.6 pm 0.2\)\% interference visibility with a local oscillator. This simultaneous achievement of state-of-the-art metrics demonstrates an adaptable platform for quantum networking.
