广义类W态的自旋压缩

Spin Squeezing of General W-class State

利用自旋压缩研究了广义类W态的纠缠特性。结果表明,自旋压缩的大小仅仅只由叠加系数决定,而与相对相位的大小无关。

We investigate the entangled property of general W-class state withspin squeezing. It is shown that spin squeezing parameter is only dependent on the superposition coefficients and is inde- pendent of the relative phase.
