研究了k光子Jaynes-Cummings模型光场的熵压缩,讨论了光子数k和原子的初始状态对光场熵压缩的影响.结果表明,随光子数k的增大,光场的位置熵压缩愈趋明显,动量熵压缩量减小;当k≥3时,位置熵始终是被压缩的.原子的初态对光场的熵压缩也有一定的影响.

We investigated the field entropy squeezing of k-photon Jaynes-Cummings model,discuss the influence of the photon number k and the initial state of the atom on the entropy squeezing. The results show that with the photon numberk increasing,the position entropy squeezing will be enhanced and the momentum entropy squeezing reduced. When k≥3,the position entropy is always squeezed. The initial state of the atom also shows some influence on the entropy squeezing.-
