通过使用多个常规的单光子计数模块(SPCM)来代替光子数分辨探测器,研究了不同量子态的非经典判据。标准的界限是从基于三个或四个SPCM的系统得出的。总体效率和背景都被考虑在内。用热光和相干光的实验结果与理论分析相吻合。与光子数分辨探测器相比,使用类似Hanbury Brown-Twiss方案的多个SPCM可以更好地揭示光场的非经典特性,而且对效率的要求也不是很严格。提出了一些改进二元响应SPCM对不同量子态的检测性能的建议。
By employing multiple conventional single-photon counting modules (SPCMs), which are binary-response detectors, instead of photon number resolving detectors, the nonclassicality criteria are investigated for various quantum states. The bounds of the criteria are derived from a system based on three or four SPCMs. The overall efficiency and background are both taken into account. The results of experiments with thermal and coherent light agree with the theoretical analysis. Compared with photon number resolving detectors, the use of a Hanbury Brown–Twiss-like scheme with multiple SPCMs is even better for revealing the nonclassicality of the fields, and the efficiency requirements are not so stringent. Some proposals are presented which can improve the detection performance with binary-response SPCMs for different quantum states.
