维格纳函数的负性作为非经典性的指示器

Negativity of the Wigner function as an indicator of nonclassicality

Anatole Kenfack, Karol Zyczkowski

摘要:

提出了一种基于Wigner函数负部分体积的量子态非经典性度量。我们分析了Fock态、压缩位移Fock态和两个高斯波包相干叠加的类猫态的这个量。

英文摘要:

A measure of nonclassicality of quantum states based on the volume of the negative part of the Wigner function is proposed. We analyze this quantity for Fock states, squeezed displaced Fock states and cat-like states defined as coherent superposition of two Gaussian wave packets.
