We demonstrated the coincidence measurement of quantum light by superconducting nanowire single-photon detectors with a single-flux-quantum (SFQ) circuit as a signal processing circuit. By the quantum state tomography of a polarization-entangled photon pair, we evaluated the detection system based on the SFQ coincidence circuit. The estimated fidelity was almost the same value as that measured by using a detection system based on a conventional time-to-digital converter.

具有单通量量子符合电路的超导纳米线单光子探测器的纠缠光子对探测

我们展示了通过使用单通量量子 (SFQ) 电路作为信号处理电路的超导纳米线单光子探测器对量子光的符合测量。通过偏振纠缠光子对的量子态断层扫描,我们评估了基于SFQ符合电路的检测系统。估计的保真度与使用基于传统时间数字转换器的检测系统测得的值几乎相同。
