摘要
我们提出了一种高效、可扩展和确定性的方案,可根据需要通过独立信道产生多个无差别光子。我们的设计依赖于多个单光子源,每个单光子源都与波导耦合,并与一个共同的空腔模式相互作用。空腔同步触发每个光源同时发射一个光子,并由波导收集。在最先进的电路 QED 实现中,该方案支持以 ∼MHz 的速率产生纯度达 99%、无差别和高效率的单光子。我们还讨论了同时产生多达 100 个光子的条件,其产生率高达数百千赫兹。这比以前用于玻色子采样的解复用源的效率要高出几个数量级,并能实现确定性多光子源和可扩展的光子量子信息处理。
Scalable multiphoton generation from cavity-synchronized single-photon sources
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, all interacting 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. In a state-of-the-art circuit QED implementation, this scheme supports the creation of single photons with purity, indistinguishability, and efficiency at rates of . 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 multiphoton sources and scalable quantum information processing with photons.
