【摘要】 在光子双模压缩真空态|ξ〉上增加m个光子构成光子双模压缩真空态a+m|ξ〉,利用量子力学的态叠加原理,构造出光子双模压缩真空态的叠加态|ψ〉,并通过数值计算研究了叠加态|ψ〉的非经典特性.结果表明:在一定的条件下,叠加态|ψ〉的平均光子数呈现出崩塌与复原的振荡现象,而且亚泊松特性和位相压缩都比单个a+m|ξ〉态的情况强.更多还原

【Abstract】 The superposition state from the photon-added two-mode squeezed vacum state a+m|ξ〉 is constructed,and its noclassical properties are numerically studied under the principle of superposition in quantum mechanics.The results reveal that under certain conditions,the mean photon number of the superposition state exhibits oscillating phenomenon of collapses and revivals,bot sub-Poissonian photon statistical character and the phase squeezing of the field in the superposition state are stronger than ones in the single photon-added two-mode squeezed vacuum state.更多还原
