Abstract:
A Josephson inverter gate circuit provides efficient implementation of polarity or logical inversion while eliminating the need for physically large high-efficiency magnetic transformers in the signal path. The circuit can consist of a half-twisted Josephson transmission line (JTL) or a JTL with an unshunted floating Josephson junction that produces two single flux quantum (SFQ) pulses when triggered by an SFQ input signal, which results in an output SFQ signal of reversed polarity. Implemented as a logical inverter, proper initialization of the circuit is accomplished within the signal inversion stage with flux biasing.

Claim (Index 1):
A Josephson inverter gate circuit comprising:\n an input to provide an input signal comprising at least one single flux quantum (SFQ) pulse; a Josephson transmission line (JTL) comprising at least four Josephson junctions arranged to propagate the input signal to an output, and, additionally, a floating Josephson junction in a central portion of the JTL, by which the JTL is arranged to invert the input signal into an output signal, wherein the inverter gate circuit is a reciprocal quantum logic (RQL) inverter capable of inverting the input signal encoded with RQL data encoding having SFQ pulses of either positive or negative polarity.
