Superconducting Qubit Reset with Microwave Photon Counter

The USPTO published this patent application describing a system for deterministic reset of superconducting qubits and cavity modes using microwave photon counters. The technology comprises multiple qubit-microwave photon counter pairs coupled via qubit-qubit coupling, with each pair having a qubit circuit, microwave photon counter circuit, and resonant cavity. CPC classifications include G06N 10/00 (quantum computing), H10N 60/12, H10N 69/00, and B82Y 10/00.

For companies developing superconducting quantum computing systems, this published application represents potential prior art that may affect freedom-to-operate analyses. R&D teams and patent counsel should monitor the application prosecution for any issued claims that could impact ongoing research programs. Inventors in adjacent quantum computing fields may wish to review the disclosure during their own patent filing processes.
