我们在实验上证明了一种Hong-Ou-Mandel型的双光子干涉效应，它具有一个预示的单光子态和一个热态。1550 nm通信波段的光源由两个独立的色散位移光纤通过四波混频过程产生。观察到的能见度为（82 +/- 11）%。独立源之间的这种干涉在具有独立量子比特的量子信息处理中至关重要。(c)2008年美国光学学会。
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. (c) 2008 Optical Society of America.
