Entangled coherent states and their nonclassical effects
纠缠相干态及其非经典特性

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.
