本文提出了一个制备三光子W态的实验方案。该方案基于线性光学元件、自发参量下转换产生的四个偏振纠缠光子和单光子探测。讨论了光学元件的不完整性对非局域性的影响。
We present an experimental scheme of preparing the three-photon W-state in this paper. This scheme is based on a linear optical element, four polarization-entangled photons produced in spontaneous parametric down-conversion and single-photon detection. Effects of the imperfection of optical elements on nonlocality are also discussed.
