Superconducting data alignment system

A method for aligning data to a defined phase of a clock signal at an input of a superconducting circuit, the method comprising:

• providing a first phase window of the clock signal to a first coupling circuit;
• providing a second phase window of the clock signal to a second coupling circuit, the second phase window being opposite in phase relative to the first phase window;
• providing a return-to-zero (RTZ) input pulse to each of the first and second coupling circuits to generate at least one of a first single flux quantum (SFQ) pulse from the first coupling circuit and a second SFQ pulse from the second coupling circuit;
• and
• providing the clock signal to an alignment circuit to generate an output SFQ pulse that is aligned to the clock signal in response to receiving at least one of the first and second SFQ pulses.

A reciprocal quantum logic (RQL) circuit system comprising:

• a data alignment system, the data alignment system comprising:
• a first coupling circuit configured to receive a return-to-zero (RTZ) input pulse and to generate a first RQL pulse in response to the RTZ input pulse being aligned with a first phase window of an RQL clock signal;
• a second coupling circuit configured to receive the RTZ input pulse and to generate a second RQL pulse in response to the RTZ input pulse being aligned with a second phase window of the RQL clock signal, the first and second phase windows being opposite in phase;
• and
• an alignment circuit that is configured to generate an output RQL pulse that is aligned to the RQL clock signal in response to receiving at least one of the first and second RQL pulses;
• and
• an RQL superconducting circuit that operates based on the RQL clock signal, wherein the RQL superconducting circuit receives the output RQL pulse aligned to a defined phase of the RQL clock signal at an input.
