Abstract Supercurrent fluctuation of a mesoscopic Josephson junction ( MJJ ) in the pre-sence of a dc static voltage and a time-varying quantized electromagnetic field ( QEMF) is investigated. It is shown that the fluctuation of supercurrent in the MJJ exhibits periodical oscillations with a periodicity which depends upon the rate of the classical static external voltage and the frequency of the QEMF.
