| Abstract: | We propose a quantization scheme for a non-dissipative distributed parameter circuit. Quantum fluctuations of charge and flux in the vacuum state are investigated by adopting the canonical transformation and unitary transformation method. The results indicate that in the distributing parameter circuits, quantum fluctuations are related to both the circuit parameters and the positions and the mode of signals. |
