摘要
通过引入正交基矢,连续变量形式的纠缠相干态转化成分立形式,然后用concurrence方法计算了纠缠度,同时研究了其非经典效应(压缩效应,反聚束效应).发现纠缠总是伴随着压缩效应和反聚束效应两者之一,并随相应非经典效应的增大而增大.
By introducing orthogonal basis, the entangled coherent states are converted to discrete ones. We calculate their entanglement by concurrence their nonclassical effects, such as squeezing and antibunching. We find that the entanglement always follows either one of squeezing or antibunching and the entanglement increases with the increase of one of the nonclassical effects.
