Abstract

In Josephson circuitry, the phenomenon of punchthrough is known, wherein Josephson devices fail to reset when the AC power waveform changes polarity. In order to reduce the probability of punchthrough, it is proposed to apply a small control current to the Josephson device while the device is expected to reset.
