摘要

量子电容探测器(QCDs)是一种限制散粒噪声的太赫兹探测器。辐射破坏库珀对，导致准粒子中毒的电荷量子位，读出微波谐振器。我们发现电报跃迁率分布的不对称性，解释为离散单光子事件的结果。

Evidence of 1.5 THz single-photon detection in quantum capacitance detectors via telegraph rate distribution asymmetry

Quantum Capacitance Detectors (QCDs) are shot noise limited terahertz detectors. Radiation breaks Cooper pairs, causing quasiparticle poisoning of a charge qubit, read out by a microwave resonator. We find asymmetry in the distribution of telegraph transition rates, interpreted as resulting from discrete single-photon events.
