  • Publication number: 20200168782
    Abstract: Techniques for forming quantum circuits, including connections between components of quantum circuits, are presented. A trench can be formed in a dielectric material, by removing a portion of the dielectric material and a portion of conductive material layered on top of the dielectric material, to enable creation of circuit components of a circuit. The trench can define a regular nub or compensated nub to facilitate creating electrical leads connected to the circuit components on a nub. The compensated nub can comprise recessed regions to facilitate depositing material during evaporation to form the leads. For compensated nub implementation, material can be evaporated in two directions, with oxidation performed in between such evaporations, to contact leads and form a Josephson junction. For regular nub implementation, material can be evaporated in four directions, with oxidation performed in between the third and fourth evaporations, to contact leads and form a Josephson junction.

  • Patent number: 10664640
    Abstract: A system includes a memory that stores computer executable components, and a processor executes the computer executable components stored in the memory. The computer executable components comprise: an assessment component that determines locations for mode suppression structures on a coplanar waveguide of a quantum chip having qubits; a simulation component that simulates performance of the quantum chip based on a subset of the locations for the mode suppression structures and parameters of the quantum chip, and generates a mode suppression structures placement model. A template component generates a template of specific coordinates for placement of a subset of the mode suppression structures on the quantum chip based on the mode suppression structures placement model; and a driver component employs the template to drive an auto-bonder to install the subset of the mode suppression structures on the quantum chip at the specific coordinates.
