摘要
基于介观电容存在弱耦合特性，对介观LC电路的量子效应进行了研究。研究结果表明：考虑介观电容器弱耦合效应的影响，介观LC电路将由初始的薛定谔猫态演化到压缩薛定谔猫态。并对压缩薛定谔猫态下的量子涨落进行了计算，发现压缩薛定谔猫态下磁通和电荷的量子涨落具有比薛定谔猫态下程度更高的压缩和反压缩效应。
We quantizied the mesoscopic LC circuit, based on the infirmness coupling characteristic of a mesoscopic capacitor. The studies showed： Considered the influence of the infirmness coupling effect in a mesoscopic capacitor, the mesoscopic LC circuit would evolve into squeezing Schroedinger cat state from Schrodinger cat state. And we also calculated the quantum fluctuation of both charge and magnetism flux in squeezing Schroedinger cat state. We found that the squeezed intension is stronger in squeezing Schroedinger cat state than in Schroedinger cat state.
