论文摘要
超导纳米线单光子探测器是现代量子信息科学的一种有利技术，并且正在为其他领域中最苛刻的光子计数任务带来吸引力。将这些检测器嵌入光子综合电路中，可以通过纳米光子功能化来实现其他计数能力。在这里，我们展示了如何在同一芯片上与独立的光纤光纤通道连接到可扩展数量的波导纳米电视单光子检测器。我们的插件检测器软件包托管在紧凑而便携式的闭合周期低温恒温器中，可为多达64个通道提供低温信号放大。我们展示了最新的光子计数性能，最高60％的系统检测效率，对于单个可寻址检测器的系统检测效率高达26.0 PS的时间准确性。我们的多通道单光子接收器为将来的量子通信，遥感和成像应用提供了令人兴奋的测量功能。
Superconducting nanowire single-photon detectors are an enabling technology for modern quantum information science and are gaining attractiveness for the most demanding photon counting tasks in other fields. Embedding such detectors in photonic integrated circuits enables additional counting capabilities through nanophotonic functionalization. Here we show how a scalable number of waveguide-integrated superconducting nanowire single-photon detectors can be interfaced with independent fiber optic channels on the same chip. Our plug-and-play detector package is hosted inside a compact and portable closed-cycle cryostat providing cryogenic signal amplification for up to 64 channels. We demonstrate state-of-the-art photon counting performance with up to 60 % system detection efficiency and down to 26.0 ps timing accuracy for individually addressable detectors. Our multi-channel single photon receiver offers exciting measurement capabilities for future quantum communication, remote sensing and imaging applications.
