Abstract
We consider the system of a mesoscopic Josephson junction interacting with a quantized radiation field and investigate the fluctuation properties of t he junction variables with time evolution. Our results show that, due to th e quantum entanglement between the field and junction, the mesoscopic Josep hson junction subsystem can exhibit squeezing behavior.
