title: Observation of quantum interference between a single-photon state and a thermal state generated in optical fibers.
abstract: We experimentally demonstrate a Hong-Ou-Mandel type of two-photon interference effect with a heralded single-photon state and a thermal state. The light sources in the 1550 nm telecom band are generated from two independent dispersion-shifted fibers via four-wave mixing process. The observed visibility is (82+/- 11)%. This type of interference between independent sources is crucial in quantum information process with independent qubits.
