两态叠加Schrdinger猫态光场的两种测不准态

Two Uncertainty States in Schrdinger Cat State Light Field of Superposition State with Two Quantum States

根据多模压缩态理论,详细研究了两态叠加Schr¨odinger猫态光场的压缩特性.发现:在一定的条件下,该光场将不呈现等幂次的Y和H压缩效应以及等幂次的N-Y和N-H最小测不准态;而呈现出等幂次的N-Y测不准态和N-H测不准态.

According to the theory of multi-mode squeezed states, the properties of Schr?dinger cat state light field superposition with two quantum states are studied. It finds out that under certain conditions, the light field state cannot present the effects of equal-power Y-squeezing and H-squeezing and equal-power N-Y minimum uncertainty state and N-H minimum uncertainty state, but can present equal-power N-Y uncertainty state and equal-power N-H uncertainty state.
