构造了叠加激发相干态C(α+m|α>+e~(iθ)α~(+m)|-α>),用数值计算的方法研究了θ和m对该量子态Wigner函数及其边缘分布的影响.结果表明:不论θ为何值,叠加激发相干态都能够呈现非经典性质,而且Wigner函数及其边缘分布明显受到θ和m的调节.
The superposition state C((α~(+m)|α>+e~(iθ)α~(+m)|-α>) from the excited coherent state was constructed.Dependences of Wigner function on θ and m and its marginal distributions for the superposition state were numerically investigated. It is shown that the superposition state is always able to exhibit the non-classical properties for any θ, Wigner function and its marginal distributions evidently depend on θ and m.
