A quantization scheme for an LC circuit a source was proposed and the fluctuations of the charge and the magnetic flux of the circuit in excited squeezed vacuum state are studied by using the complete quantum theory.It is shown that the quantum fluctuations of both charge and magnetic flux in the circuit are relation to both not only the circuit component and the squeezed parameter but also the degree of excitation of the quantum state.

Quantum Fluctuations of Mesoscopic Parallel Connection LC Circuit in Thermal Vacuum State

Starting from the classical equation of motion, the mesoscopic parallel LC circuit is quantized. On this basic theory, we have studied quantum fluctuations of the voltage and current of each branch in thermal vacuum state. The result shows that the quantum fluctuations of the voltage and current of each branch are related with parameter of the circuit element, and also related with temperature and decayed with time.
