【摘要】 在量子光学压缩真空态概念的基础上，借助玻色振子逆算符的性质，提出了压缩真空态的激发态的概念，导出了介观ＲＬＣ 电路在该量子态下电荷和电流的量子零点涨落，发现该涨落明显依赖于电路的元件、压缩参数以及激发态的量子数，并得到了该电路在绝对零点时的量子噪声．更多还原

【Abstract】 On the basis of the squeezed vacuum state in quantum optics, the concept of excited state for the squeezed vacuum state is presented by means of the nature of bosonic inverse operators. The quantum zero?point fluctuations both for charge and current in a mesoscopic RLC circuit are also derived.It is found that fluctuations depend explicitly on circuit units,squeezed parameter and quantum numbers of excited state. The quantum noise of this circuit at an absolute zero temperature is obtained.更多还原
