We have studied the transition rate from the zero-voltage state in a dc SQUID as a function of applied flux and temperature. We observe a crossover from thermal activation to macroscopic quantum tunneling at a flux-dependent temperature. The thermal rates are significantly suppressed, suggesting tha

The Josephson effect is one manifestation of the quantum aspect of macroscopic objects. It has been tested in various macroscopic systems to confirm their quantummechanical nature. In some of the systems, the total number of particles in the system is fixed. In such a case, the dynamics of the syst
