从无耗散的电容耦合电路的经典运动方程出发，分别研究了这一耦合电路在任一本征态下和在压缩真空态下电荷、电流的量子涨落.结果表明，两个回路中的量子噪声是相互关联的.Starting from the equation for the classical motion of a nondissipative mesoscopic capacitance coupled circuits with source,we have studied the quantum fluctuations of the charge and current in the eigenstate of the coupled circuits and in the squeezed vacuum state,respectively.The results show that the quantum fluctuations in the two circuits are correlated with each other.
