| Research Abstract |
A readout circuit using superconducting single-flux-quantum (SFQ) circuits was proposed to realize an independently addressable array of superconducting single-photon detectors (SSPDs). We designed an SSPD/SFQ interface circuit and tested it by connecting with SSPDs. The error rates of SFQ readout circuits were found to be below 10-5 and the connection of the SFQ readout circuit does not affect the detection efficiency curve observed in the SSPD.
