空间模中的高维双光子干涉效应

High-dimensional two-photon interference effects in spatial modes

Markus Hiekkamäki, Robert Fickler

摘要:

双光子干涉是一种基本的量子光学效应,在量子信息科学中有着广泛的应用。本文研究了单光路中多个横模空间双光子干涉,除了用二维空间模分束器模拟Hong-Ou-Mandel干涉外,还将该方案推广到不同的三维和四维空间模多端口中观察并合和反并合现象。空间模式内的操作,沿着一个单一的光束路径,提高了对干涉稳定性的要求,并开辟了新的途径,实现复杂的量子信息任务的线性光网络。

英文摘要:

Two-photon interference is a fundamental quantum optics effect with numerous applications in quantum information science. Here, we study two-photon interference in multiple transverse-spatial modes along a single beam-path. Besides implementing the analogue of the Hong-Ou-Mandel interference using a two-dimensional spatial-mode splitter, we extend the scheme to observe coalescence and anti-coalescence in different three and four-dimensional spatial-mode multiports. The operation within spatial modes, along a single beam-path, lifts the requirement for interferometric stability and opens up new pathways of implementing linear optical networks for complex quantum information tasks.
