本文提出了一种仅用热噪声作为探针来重建光子数分布的有效方法。该方法使用了最少数量的预校准量子器件；只有一个开关单光子探测器是足够的。实验结果表明，该方法是可行的。还有双光子态。该方法对实验缺陷是稳定的，并提供了一个直接的，用户友好的量子诊断工具。
We present an efficient and robust method for the reconstruction of photon number distributions by using solely thermal noise as a probe. The method uses a minimal number of precalibrated quantum devices; only one on-off single-photon detector is sufficient. The feasibility of the method is demonstrated by the experimental inference of single-photon, thermal. and two-photon states. The method is stable to experimental imperfections and provides a direct, user-friendly quantum diagnostics tool.
