摘要
引入了一类新的量子态——一般薛定谔猫态 ,它由两个平均光子数不同的相干态叠加而成 ;同时研究了在此态上表现出的光子数分布和压缩效应 .结果表明 ,在该态下平均光子数呈双脉冲分布形式 ,而压缩只出现在正交分量 Y2
A new class of quantum state, the general Schrdinger cat state, is presented, which is a quantum superposition of two coherent states with macroscopically different average photon number and different phase. The quasi probability distribution and squeezing effect have been discussed in the proposed states. The results show that distribution of average photon number exhibits bi pulse distribution and only one of the quadratures is squeezed.
