摘要： 介绍了量子光学中常见的双光子纠缠态关联函数的两种求法，第一种方法是利用产生湮没算符的对易关系来求解；第二种方法是应用“二次量子化”的方法来计算，这种方法不需要用对易关系，计算简便．
关键词: 双光子纠缠态, 关联函数, 对易关系, 二次量子化
Abstract: Two solutions of correlation function of entangled photon pair in quantum optics are introduced. The first method uses the commutation relation of raising and lowering operator; the second method is called the second quantization. For the latter, one does not need to use any commutation relation, thus it is very convenient.
Key words: two-photon entangled state, correlation function, commutation relation, second quantization
