摘要
通过保持非耗散介观LC电路的固有频率不变 ,而使电路参数作阶跃函数变化 ,就可将介观LC电路由初始的偶相干态制备到压缩偶相干态 ;在压缩偶相干态下 ,介观电路系统不仅有非经典的量子压缩效应 ,而且有非经典的反聚束效应 .
By keeping the frequency of non-dissipative mesoscopie LC circuit a constant and its parameter varying with the step function, the quantum state of the circuit evolves to a squeezed even coherent state from the initial even coherent state. The nonclassical properties, not only squeezing but also antibunching effects, appear in the circuit by adjusting its inductor parameter under the squeezed even coherent state.
