  • Qubit control electronics
    Patent number: 11929711
    Abstract: A device for generating a qubit control signal includes: a first signal envelope generator circuit including a first multiple of signal sources, in which an output of each signal source of the first multiple of signal sources is combined to provide a first cumulative output; and a first mixer circuit coupled to the first signal envelope generator circuit, in which the first cumulative output is coupled to a first input of the first mixer circuit, and an output of the first mixer circuit includes a first qubit control signal.
    Type: Grant

  • IMPEDANCE MATCHING USING KINETIC INDUCTORS
    Publication number: 20220029589
    Abstract: A circuit device includes a semiconductor device and an impedance matching network. The impedance matching network includes a superconductor material forming at least one inductor of the circuit device, and the superconductor material exhibits a kinetic inductance per unit square when in a superconducting state. The impedance matching network is configured to transform an impedance of the semiconductor device to match a predetermined second impedance during operation of the circuit device.
