Great interest revolves around the development of new strategies to efficiently store and
manipulate quantum information in a robust and decoherence-free fashion. Several …

The Josephson effect was theoretically predicted by Brian Josephson in 1962. Experimental
observation of the stationary Josephson effect was firstly realized by Anderson and Rowell …

The aim of this review is the analysis of dynamical properties of Josephson junctions (JJ)
