论双模压缩算符的自然表象——纠缠态表象

摘要

利用简洁的幺正变换得到双模压缩算符在纠缠态中的表示，使用同样的方法可得到双模压缩算符在坐标和动量本征态中的表示．%Using a simple unitary transformation,this paper derives the expression of two-mode squeezing operator in the entangled state representation.Same method is applied in obtaining the two-mode squeezing operator in the coordinate and momentum representation.
