光学态的非经典性是玻色子场的一个重要特性，是量子信息处理的重要资源。从定量的角度研究了量子过程中非经典性的产生，介绍了基于Wigner-Yanase斜信息和相干态的三种量子光学过程非经典性的信息论测度，并通过几个著名的单模量子过程说明了它们的物理意义.
Nonclassicality of optical states, as a key characteristic of bosonic fields, is a valuable resource for quantum information processing. We investigate the generation of nonclassicality in quantum processes from a quantitative perspective, introduce three information-theoretic measures of nonclassicality for quantum-optical processes based on the Wigner–Yanase skew information and coherent states, and illustrate their physical significance through several well-known single-mode quantum processes.
