摘要
研究了相干态│α〉的相位相反态│-α〉的量子相位分布,通过数值计算比较分析了相干态│α〉的相位相反态│-α〉的量子相位分布.结果发现相位相反态│-α〉的量子相位分布量子相位分布振幅峰值移动的位置相差为π.
The Quantum phase distribution properties of a coherent state｜α〉＇s opposition state ｜-α〉 is studied in this paper by using a concept of the Pegg-Bamett phase.It is found that the distributing of ｜-α〉 state present periodicity：distribution center is displaced 180° which is compared with the coherent state,changing with displace distance of the coherent state that is displaced from a vacuum state in complex plan.
