叠加相干态的Wigner函数及其边缘分布

The Wigner Function and its Marginal Distributions for Superposition of the Coherent State

构造了叠加相干态|αθ〉=C(|α〉+eiθ|-α〉),研究了θ和α对该量子态Wigner函数及其边缘分布的影响.结果表明:Wigner函数及其边缘分布明显受到θ和α的调节.

The superposition state ｜αθ〉=C（｜α〉＋e｜-α〉） from the coherent state was constructed. The θ and α dependences of the Wigner function and its marginal distributions for the superposition state were investigated. It is shown that the Wigner function and its marginal distributions are evidently depended on θ and α.
