The non-classical characteristic of optical field with negative P representation;
负P表示光场的非经典特性
The Wehrl′s Entropy and Shannon′s entropy for the non-classical optical fields with negative P representation are studied in this paper.
研究了负P表示非经典光场的Wehrl熵和Shannon熵与场参数m和平均光子数n-的关系,结果显示,负P表示的非经典光场的Wehrl熵随着场参数m和平均光子数的增大而减小,当n-增大到一定程度时Wehrl熵趋向于一个不变的常数。
