摘要

我们采用时频投影测量，以量子有限的精度估计物体之间任意小的距离。我们通过实验解决了比其带宽小10倍的单光子水平信号的非相干混合物之间的时间和光谱分离。

Quantum-limited time-frequency estimation through mode-resolved measurements

We employ time-frequency projective measurements to estimate arbitrarily small separations between objects with quantum-limited precision. We experimentally resolve temporal and spectral separations between incoherent mixtures of single-photon level signals ten times smaller than their bandwidths.
