论文摘要
光子学提供了一种实施量子步行的有效方法，这是经典随机步行的量子类似物，该量子模拟展示了具有潜在应用的丰富物理学。但是，大多数光子量子步道不涉及光子相互作用，这限制了它们探索强相关的光物理物理学的潜力。我们建议使用单个Atom Beamsplitter网络进行牢固相互作用的离散时间量子量子行走。我们计算两个光子情况下量子步行的输出统计，这揭示了光子的紧密转运。特别是，步行可以表现出类似玻色孔的或类似费米的统计量，可以通过在选择后进行两光子检测时间间隔来调整。同样，在某些条件下，步行可以将不同类型的两光子结合状态分为不同的输出端口。这些独特的现象表明，我们的量子步行是一个有趣的平台，旨在探索强烈相关的量子多体光状态。最后，我们提出了基于时间多形的合成维度的实验实现。
Photonics provide an efficient way to implement quantum walks, the quantum analogue of classical random walk that demonstrates rich physics with potential applications. However, most photonic quantum walks do not involve photon interactions, which limits their potential to explore strongly-correlated many-body physics of light. We propose a strongly interacting discrete-time photonic quantum walk using a network of single atom beamsplitters. We calculate output statistics of the quantum walk for the case of two photons, which reveals the strongly-correlated transport of photons. Particularly, the walk can exhibit either boson-like or fermion-like statistics which is tunable by post-selecting the two-photon detection time interval. Also, the walk can sort different types of two-photon bound states into distinct pairs of output ports under certain conditions. These unique phenomena show that our quantum walk is an intriguing platform to explore strongly-correlated quantum many-body states of light. Finally, we propose an experimental realization based on time-multiplexed synthetic dimensions.
