量子连续测量：输出的频谱
Quantum continual measurements: the spectrum of the output
摘要：
当一个量子系统被连续监测时，测量的结果是一个随机过程。当输出过程平稳时，至少在长期内，可以引入过程的谱并研究其性质。用于量子光学系统的典型连续测量是所谓的零差检测。在本文中，我们将展示如何海森堡不确定性关系引起的零差谱的可能性的特征界限，我们讨论了这是如何与典型的量子压缩现象。
英文摘要：
When a quantum system is monitored in continuous time, the result of the measurement is a stochastic process. When the output process is stationary, at least in the long run, the spectrum of the process can be introduced and its properties studied. A typical continual measurement for quantum optical systems is the so called homodyne detection. In this paper we show how the Heisenberg uncertainty relations give rise to characteristic bounds on the possible homodyne spectra and we discuss how this is related to the typical quantum phenomenon of squeezing.
