摘要：
The interaction between a mesoscopic Josephson junction and a quantized electromagnetic field is discussed quantum mechanically. Within the external field approximation, it is shown that if the field is prepared in a coherent state and the junction is initially in its lowest energy level, squeezing can occur in such a system.
