Entangled State Preparation And Application

At first, we put forward a method to prepare an entangled state of two superconducting quantum interference devices in a thermal cavity with the assistance of a microwave pulse. This method is insensitive to the cavity field stats and the cavity decay. And then as an application of entangled states, we propose a scheme to teleport an unknown state by using entangled states. Our scheme is feasible no matter what Charlie's measurement is .
