| 摘 要： | 提出了一种求解EPR型连续变量纠缠态在Fock表象中的具体形式的方法.该方法利用量子场论中的正规乘积的性质,通过对正规乘积形式的玻色子算符函数的运算,导出了Fock表象中两粒子EPR型连续变量纠缠态(即两粒子算符X1-X2和P1 P2的共同本征态)的具体形式.该方法可以进一步推广至多粒子EPR型纠缠态相应具体形式的求解.因而,这是一种求解此类纠缠态在Fock表象中具体形式的普遍技术.

| Abstract: | The method getting the specific form of EPR-type entangled state of continuous variable in Fock representation is proposed.The specific form of bipartite EPR entangled state in Fock representation is derived by using the properties of normally ordered product(NOP) and operating the function of boson operators in the form of NOP.Furthermore,the method is applied to getting the specific form of multi-partite EPR entangled state in Fock representation.So,it is a general method. |
