  • Mitigation of readout error in a quantum computation
    Patent number: 11966813
    Abstract: Embodiments are provided for error mitigation in quantum programs. In some embodiments, a system can include a processor that executes computer-executable components stored in memory. The computer-executable components include a compilation component that causes encoding of one or more qubits according to a circular repetition code at a time after operations on the one or more qubits and before readout.
    Type: Grant

  • MEASURING A N-DIMENSIONAL QUANTUM SYSTEM
    Publication number: 20240119328
    Abstract: The present disclosure relates to a quantum system of dimension M comprising a transmon device. The transmon device is in an initial state ?ini which is restricted to a state ?S of a N-dimensional quantum system embedded in the quantum system, where N<M. The transmon device is configured to receive a sequence of pulses for transforming the initial state ?ini to a state ?ext of the quantum system. The transmon device is connected to a readout that is configured to perform a projection-valued measure (PVM) of the transmon device in its state ?ext.
