We consider a mesoscopic Josephson junction in a circular superconducting ring which encloses a magnetostatic flux. It is shown that the state of the junction can evolve in a quantum superposition of two coherent states. It is also shown that the destructive interference between these two states sup
Photon-assisted macroscopic quantum tunneling in a slightly current-biased Josephson junction with a small capacitance and a low damping factor is proposed to occur between the quantized energy levels in adjacent potential wells by photon absorption or emission. The tunneling rate is calculated by t
