Abstract

The well known Q parameter introduced by Mandel (1958) is generalized to higher orders. The photodetection of a cavity radiation is considered as continuous quantum measurement which consists of one-count and no-count processes. The evolutions of the generalized Q parameters under both the one-count and the no-count processes are studied, emphasizing their relevance to the classical or non-classical characteristics of the radiation.

连续光探测下的广义Q参数及其演化
由Mandel(1958)引入的著名的Q参数被推广到高阶。腔辐射的光探测被认为是由一计数和无计数过程组成的连续量子测量。研究了一计数和无计数过程下广义Q参数的演化,强调了它们与辐射的经典或非经典特性的相关性。
