  • Quantum Computer with Improved Quantum Optimization by Exploiting Marginal Data
    Publication number: 20230289636
    Abstract: A quantum optimization system and method estimate, on a classical computer and for a quantum state, an expectation value of a Hamiltonian, expressible as a linear combination of observables, based on expectation values of the observables; and transform, on the classical computer, one or both of the Hamiltonian and the quantum state to reduce the expectation value of the Hamiltonian.
    Type: Application
    Filed: April 5, 2023
    Publication date: September 14, 2023
    Inventors: Peter Douglas Johnson, Maxwell D. Radin, Jhonathan Romero, Yudong Cao, Amara Katabarwa
  • Simulating errors of a quantum device using variational quantum channels
    Patent number: 11288121
    Abstract: A hybrid quantum classical (HQC) computer system, which includes both a classical computer component and a quantum computer component, implements indirect benchmarking of a near term quantum device by directly benchmarking a virtual quantum machine that models the quantum computer device and that has a level of errors that corresponds to the level of errors associated with the quantum computer device. The direct benchmarking, conducted using quantum error correction tools, produces a probability distribution of error syndromes that may be used as a probability distribution of error syndromes for the quantum computer device.
    Type: Grant

  • Computer Systems and Methods for Computing the Ground State of a Fermi-Hubbard Hamiltonian
    Publication number: 20210272002
    Abstract: A quantum computer or a hybrid quantum-classical (HQC) computer leverages the power of noisy intermediate-scale quantum (NISQ) superconducting quantum processors at and/or beyond the supremacy regime to evaluate the ground state energy of an electronic structure Hamiltonian.
