使用独立产生的光子作为输入可观测多光子干涉，最简单情形下这些光子在分束器处相遇，产生光子透射与反射间的量子干涉。本文展示可通过模式交换操作实现非局域多光子干涉，该操作在两个空间分离的干涉仪输出端检测到的光子间产生纠缠；输出光子的空间分离特性，使该多光子干涉的实现特别适用于向不同方分发量子信息的量子协议。
英文摘要
Multi-photon interference can be observed using independently generated photons as input. In the most simple case, these photons meet up at a beam splitter, resulting in quantum interference between transmission and reflection of the photons. Here, we show that non-local multi-photon interference can be implemented by using a mode swap operation to generate entanglement between the photons detected in the outputs of two spatially separated interferometers. The spatial separation of the output photons makes this implementation of multi-photon interference particularly suitable for quantum protocols that distribute quantum information to different parties.
