Abstract
We study chaos synchronization between Josephson junctions coupled uni-directionally with time-delay and demonstrate the possibility of high quality synchronization with numerical simulations of such systems. We also investigate the effect of the parameter mismatches on the synchronization quality. The role of noise in the synchronization is also elucidated. The results are important for obtaining the high power system of Josephson junctions, which is promising for practical applications.
