| Abstract: | Starting from the classical equation of motion for a mesoscopic capacitancecoupling circuit, we study the quantum fluctuations of charge and current of themesoscopic capacitance coupling circuit in a displaced squeezed Fock state. Itis found that the quantum fluctuations of charge and current in each componentcircuit depend on the devices of two circuits and the squeezing parameters, whilethe fluctuations do not depend on displacement parameters. |
