| 摘 要： | 借鉴阻尼谐振子正则量子化的方法，实现了对耗散介观RLC串并联电路的量子化，并在此基础上，研究了真空态下电路中电荷和自感磁通链、电压和电流的量子涨落。结果表明，电路中电荷和自感磁通链、电压和电流在真空态下都具有各自的量子涨落，且量子涨落及量子涨落积的大小皆与电路中的器件参数有关，并随时间按指数规律衰减。

| Abstract: | By using canonical quantization method of damped harmonic oscillator, the quantum of dissipative mesoscopic RLC series and parallel circuit was realized. And on this basis, the quantum fluctuations of charge and inductance flux linkage as the same as voltage and current in circuit under vacuum state were also studied through this research methods. The results show that charge and inductance flux linkage as the same as voltage and current in circuit under vacuum state respectively exist quantum fluctuations. And the size of the quantum fluctuations and quantum fluctuations plot all depend on device parameters in the circuit, which decaying exponentially with time. |
