Preparation of Schr?dinger cat state via a mesoscopic LC circuit
利用介观LC电路制备薛定谔猫态

A scheme is presented for preparing the superposition of coherent states,i.e.,Schr?dinger cat states. These states can be generated by the action of an external impulse functional signal on initial vaccum state of a mesoscopic LC circuit. The nonclassical squeezing properties appear in the circuit under the Schr?dinger cat states.
