论文摘要
我们提出了一个有效，可扩展和确定性的方案，以按需在独立的通道上产生多个难以区分的光子。我们的设计依赖于多个单光子源，每个源耦合到波导，并且它们都与公共腔模式相互作用。腔体同步并触发每个源同时发射一个光子，这是由波导收集的。对于最先进的电路QED实施，该方案支持以纯度，无法区分的性能和$ 99 \％$ $ \ sim $ MHz的效率创建单个光子。我们还讨论了同时生产多达100个光子与数百kHz同时生产的条件。这是比以前的玻色子采样来源更有效的数量级，并可以实现确定性的多光子源和使用光子的可扩展量子信息处理。
We propose an efficient, scalable, and deterministic scheme to generate multiple indistinguishable photons over independent channels, on demand. Our design relies on multiple single-photon sources, each coupled to a waveguide, and all of them interact with a common cavity mode. The cavity synchronizes and triggers the simultaneous emission of one photon by each source, which are collected by the waveguides. For a state-of-the-art circuit QED implementation, this scheme supports the creation of single photons with purity, indistinguishability, and efficiency of $99\%$ at rates of $\sim $MHz. We also discuss conditions to produce up to 100 photons simultaneously with generation rates of hundreds of kHz. This is orders of magnitude more efficient than previous demultiplexed sources for boson sampling and enables the realization of deterministic multi-photon sources and scalable quantum information processing with photons.
