Patent number: 11960970Abstract: Systems and techniques that facilitate strategic pausing for quantum state leakage mitigation are provided. In various embodiments, a system can comprise a detection component that can detect a quantum state leakage associated with one or more qubits. In various aspects, the system can further comprise a pause component that can, in response to detecting the quantum state leakage, generate a time pause prior to execution of a quantum circuit on the one or more qubits. In various embodiments, the pause component can generate the time pause after execution of a previous quantum circuit on the one or more qubits, where the quantum state leakage arises during the execution of the previous quantum circuit. In some cases, the quantum state leakage can decay during the time pause.Type: GrantFiled: November 12, 2020Date of Patent: April 16, 2024Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Oliver Dial, Antonio Corcoles-Gonzalez, Maika Takita, David C.
