摘要：

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 ar e calculated.
