|Abstract: ||Vortices circulating in a ring made from a Josephson array in the insulating phase are studied.
The ring contains a ‘dual Josephson junction’ through which the vortices tunnel. External non-classical
microwaves are coupled to the device. The time evolution of this two-mode fully quantum mechanical
system is studied, taking into account the dissipation in the system. The effect of the quantum statistics
of the photons on the quantum statistics of the vortices is discussed. Entropic calculations quantify the
entanglement between the two systems. Quantum phenomena in the system are also studied through
Wigner functions. After a certain time (which depends on the dissipation parameters) these quantum
phenomena are destroyed due to dissipation.|
