摘要

理论证明，相对于非挤压态，薛定谔猫的挤压态可以达到很高的量子灵敏度。为了实现薛定谔猫的挤压态，使用了非线性光学晶体中的参数过程。为了使薛定谔猫在有位移和无位移时的挤压状态可视化，需要计算维格纳函数的值。

Quantum sensitivity of squeezed Schrodinger cat states

Theoretically it is shown that high quantum sensitivity of the squeezed state of the Schrodinger cat relative to the non-squeezed state can be achieved. For realization of squeezing the Schrodinger cat state, a parametric process in a nonlinear optical crystal is used. To visualize the squeezed state of the Schrodinger cat with and without a displacement, the values of the Wigner functions are calculated.
