Abstract： Starting from the equation of motion for a circuit including resistor, inductor and capacitor (RLC), we study the quantum fluctuations of charge and magnetic flux of a mesoscopic RLC circuit in a displaced squeezed Fock state. It is found that the fluctuations of charge and magnetic flux do not depend on the displacement parameter and there exist squeezing effects between them. We also show how to generate the displaced squeezed Fock state in the RLC circuit.
