| 摘 要： | 从激发双模压缩真空态a+mb+m|ξ>出发构造了叠加态|Ψ>,研究了|Ψ>的量子统计特性.结果表明:在一定的条件下,随着相位差的变化,叠加态|Ψ>的平均光子数出现类似于Rabi振荡的崩塌与复原现象,而且与单个激发双模压缩真空态a+mb+m|ξ>相比,在叠加态|Ψ>中光场的相位压缩和亚泊松光子统计特性都得到了加强.

| Abstract: | The superposition state from the excited two mode squeezed vacuum states is constructed,and its nonclassical properties are studied.Under certain conditions,as the phase difference changes,the mean photon number of the superposition state exhibits oscillating phenomenon of collapses and revivals in a manner similar to that of Rabi oscillation,sub Poissonian photon statistical character and phase squeezing of the field in the superposition states are stronger than ones in the single excited two mode squeezed vacuum state. |
