| 摘 要： | 通过量子化LC电路,运用全量子理论研究了在激发压缩真空态下介观LC电路中电荷、磁通量的量子涨落。结果表明,该电路中电荷、磁通量涨落的大小不仅与电路器件及压缩参数有关,而且与量子态的激发次数有关。

Quantum Fluctuation of Mesoscopic Circuit in Excited Squeezed Vacuum State |
| |
| Abstract: | 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. |

| Keywords: | mesoscopic circuit excited squeezed vacuum state quantum fluctuation |
