熵测不准关系与光场的熵压缩

Entropic Uncertainty Relation and Entropic Squeezing of the Field

用熵作为光场量子涨落的量度 ,根据熵测不准关系 ,建立了熵压缩的概念 ,具体研究了光场与原子相互作用时的熵压缩。结果显示 ,熵压缩实现了对光场压缩效应的高灵敏量度。

The concept of entropic squeezing is established and the entropic squeezing of the field interacting with the atom is investigated by regarding the entropy as a measure of quantum fluctuation and according to entropy uncertainty relation. The results show that the entropic squeezing is a high sensitive measure for the squeezing effect of the field.
