摘　　要：构造了增加光子奇(偶)对相干态并用数值模拟方法研究了它们的非经典性质.结果表明,增加光子奇(偶)对相干态都具有光子统计的亚泊松分布以及反聚束效应等非经典性质,是新型量子光场.在奇(偶)对相干态的两个场模上增加光子,都可以增强光场光子统计的亚泊松分布特性.The photon-added odd pair coherent states and photon-added even pair coherent states are constructed,and their nonclassical properties are studied with numeric simulation method.The results show that the constructed states are new quantum optical fields that exhibit the nonclassical properties such as the sub-poissonian distribution characters of photon statistics and the antibunching effect.When the photons are added to the two modes of the odd（even） pair coherent states,the sub-poissonian distribution characters of photon statistics can be obviously enhanced.
