  • System and method for controlling superconducting quantum circuits using single flux quantum logic circuits
    Patent number: 9425804
    Abstract: A system and methods for controlling superconducting quantum circuits are provided. The system includes at least one superconducting quantum circuit described by multiple quantum states, and at least one single flux quantum (“SFQ”) control circuit configured to generate a voltage pulse sequence that includes a plurality of voltage pulses temporally separated by a pulse-to-pulse spacing timed to a resonance period. The system also includes at least one coupling between the at least one superconducting quantum circuit and the at least one SFQ control circuit configured to transmit the voltage pulse sequence generated using the SFQ control circuit to the at least one superconducting quantum circuit. In some aspects, the system further includes a controller system configured to optimize the pulse-to-pulse spacing to minimize a gate infidelity due to at least one of a timing error, a timing jitter and a weak qubit anharmonicity.
