Interfacing with superconducting circuitry

Embodiments of the present disclosure include techniques for interfacing with superconducting circuits and systems. In one embodiment, the present disclosure includes interface circuitry, including driver circuits and/or receiver circuits to send/receive signals with a superconducting circuit. In another embodiment, the present disclosure includes superconducting circuits and techniques for generating a trigger signal from and external clock that is based on a superconducting resonator. In yet another embodiment, the present disclosure includes superconducting data capture circuits that may be used to couple external data to and/or from superconducting logic.
