论文摘要
我们在使用适当设计的量子标尺检测相位空间位移的框架内得出了经典的Optics Wiener-Khintchine定理的量子版本。引入了基于相速度的量子相互相干函数,其中包括检测器的贡献。我们获得了一个通用平等,将分辨率与连贯性联系在一起。这是高斯州和数量状态的案例。
We derive a quantum version of the classical-optics Wiener-Khintchine theorem within the framework of detection of phase-space displacements with a suitably designed quantum ruler. A phase-pace based quantum mutual coherence function is introduced that includes the contribution of the detector. We obtain an universal equality linking resolution with coherence. This is illustrated with the case of Gaussian states and number states.
