System and method for controlling superconducting quantum circuits using single flux quantum logic circuits

A method for controlling superconducting quantum circuits, the method comprising:

• providing at least one superconducting quantum circuit described by multiple quantum states and coupled to at least one single flux quantum (“SFQ”) control circuit;
• generating, using the at least one SFQ control circuit, a voltage pulse sequence that includes a plurality of voltage pulses temporally separated by a pulse-to-pulse spacing;
• and
• applying the voltage pulse sequence to the at least one superconducting quantum circuit to achieve an excitation consistent with a target transition between the multiple quantum states.
