压缩粒子数态中振幅k次幂的压缩效应

THE kTH POWER SQUEEZING OF THE FIELD AMPLITUDE IN SQUEEZED NUMBER STATES

研究了在压缩粒子数态（ＳＮＳ）中振幅ｋ次幂的压缩效应（ＡＫＰＳ），导出有关压缩效应的普遍性公式，并用数值计算的方法，得到了前四次幂ｋ＝１，２，３和４的有关压缩特性，结果表明：这种压缩特性在光学通信领域有着一定的应用前景。

We have studied the0 amplitude kth power squeezing in squeezed number statesand derived the general forrnulas related to the squeezing effect.The squeezingproperties have been obtained for the cases of k=1,2,3 and 4 by means of nume-rical calculation,The results show that the AKPS has favourable applications inoptical communication.
