Abstract
The quantum fluctuations of charges and currents of mesoscopic capacitance coupled circuit with mutual inductance are studied by using canonical transformation and unitary transformation. The results show that when the components of the circuit are given, especially when the value of L1 = L2 is very small, with the increasing of coupling extent, the quantum fluctuations of charges in one loop of circuit decrease obviously, while those charge of the other loop increase obviously.
