System And Method For Controlling Superconducting Qubits Using Single Flux Quantum Logic
WARF: P190164US01

Inventors: Robert McDermott, Maxim Vavilov, Kangbo Li

The Invention
A system and method for controlling superconducting qubits is provided. In some aspects the method includes assembling, using a controller of a quantum computing system, a pulse subsequence that comprises pairs of voltage pulses timed symmetrically with respect to a period corresponding to a qubit frequency of a superconducting qubit in the quantum computing system. The method also includes generating, using the controller, a pulse sequence using a repetition of a pulse subsequence. The method further includes controlling the superconducting qubit by applying the pulse sequence to the superconducting qubit using a single flux quantum (“SFQ”) driver coupled thereto.
