  • QUANTUM PROCESSING UNIT COMPRISING ONE OR MORE SUPERCONDUCTING QUBITS BASED ON PHASE-BIASED LINEAR AND NON-LINEAR INDUCTIVE-ENERGY ELEMENTS
    Publication number: 20230371404
    Abstract: A quantum processing unit is disclosed. The quantum processing unit includes at least one superconducting qubit based on phase-biased linear and non-linear inductive-energy elements. A superconducting phase difference across the linear and non-linear inductive-energy elements is biased, for example, by an external magnetic field, such that quadratic potential energy terms of the linear and non-linear inductive-energy elements are cancelled at least partly. In a preferred embodiment, such cancellation is at least 30%. The partial cancellation of the quadratic potential makes it possible to implement a high-coherence high-anharmonicity superconducting qubit design.
    Type: Application
