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 8):
The circuit of  claim 1 , wherein the JTL comprises:\n an input end comprising the input connected to an input node and:\n a first inductor connected between the input node and a first node; \n a first Josephson junction of the at least four Josephson junctions connected between the first node and a circuit ground; \n a second inductor connected between the first node and a second node; \n a third inductor connected between the second node and a third node; and \n a second Josephson junction of the at least four Josephson junctions connected between the third node and the circuit ground; \n an output end comprising the output connected to an output node and:\n a third Josephson junction of the at least four Josephson junctions connected between a fifth node and the circuit ground; \n a fourth inductor connected between the fifth node and a sixth node; \n a fifth inductor connected between the sixth node and a seventh node; \n a fourth Josephson junction of the at least four Josephson junctions connected between the seventh node and the circuit ground; and \n a sixth inductor connected between the seventh node and the output node; \n wherein the central portion connects the input end and the output end, the central portion further comprising a transformer-coupled DC flux bias injection source configured to inject \u03a6 0 /2 of current.
