Patent number: 11960972Abstract: In a general aspect, input data for a computer process are preprocessed by a preprocessor unit that includes a quantum processor. In some aspects, a preprocessor unit obtains input data for a computer process that is configured to run on a computer processing unit. Randomized parameter values are computed for variable parameters of a quantum logic circuit based on the input data. A classical processor in the preprocessor unit computes the randomized parameter values from the input data and a set of random numbers. A quantum processor in the preprocessor unit produces quantum processor output data by executing the quantum logic circuit having the randomized parameter values assigned to the variable parameters. Preprocessed data generated based on the quantum processor output data are then provided as the input for the computer process configured to run on the computer processing unit.Type: GrantFiled: January 6, 2023Date of Patent: April 16, 2024Assignee: Rigetti & Co, LLCInventors: Johannes Sebastian Otterbach, Christopher Mogan Wilson, Marcus Palmer da Silva, Nikolas Anton Tezak, Gavin Earl Crooks

Publication number: 20230368061Abstract: In a general aspect, a quantum streaming kernel processes a data stream. In some aspects, an input stream of data is converted to an output stream of data by repeatedly receiving new portions of the input stream; encoding each new portion into an internal quantum state of a quantum processor; measuring a first part of the internal quantum state while maintaining coherence of a second part of the internal quantum state; and producing the output stream of data based on the measurements. In some cases, a history of the input stream is preserved by the coherence of the internal quantum state, and the measurements contain information based on the history of the input stream.Type: ApplicationFiled: May 15, 2023Publication date: November 16, 2023Applicant: Rigetti & Co, LLCInventors: Nikolas Anton Tezak, Marcus Palmer da Silva, Robert Stanley Smith, Christopher Mogan Wilson

Patent number: 11112842Abstract: In a general aspect, a tunable qubit device is identified that exhibits a frequency-dependent energy relaxation process in a quantum processor cell. The frequency-dependent energy relaxation process is produced by a material defect in the quantum processor cell. A first qubit frequency associated with a first relaxation time of the tunable qubit device is identified and a second qubit frequency associated with a second relaxation time of the tunable qubit device is identified. The second relaxation time is shorter than the first due to the frequency-dependent energy relaxation process produced by the material defect. The tunable qubit device is operated at the first qubit frequency while processing quantum information in the quantum processor cell. The tunable qubit device is tuned from the first qubit frequency to the second qubit frequency. A qubit state of the qubit device is reset by the frequency-dependent energy relaxation process produced by the material defect.Type: GrantFiled: October 3, 2018Date of Patent: September 7, 2021Assignee: Rigetti & Co, Inc.Inventors: Robert Stanley Smith, Nikolas Anton Tezak
