Abstract: A method of fabricating a carrier chip for distributing signals among circuit elements of a quantum computing device, includes: providing a multilayer wiring stack, the multilayer wiring stack comprising alternating layers of dielectric material and wiring; bonding a capping layer to the multilayer wiring stack, in which the capping layer includes a single crystal silicon dielectric layer; forming a via hole within the capping layer, in which the via hole extends to a first wiring layer of the multilayer wiring stack; forming an electrically conductive via within the via hole and electrically coupled to the first wiring layer; and forming a circuit element on a surface of the capping layer, in which the circuit element is directly electrically coupled to the electrically conductive via.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for parameterization of physical dimensions of discrete circuit components for component definitions that define discrete circuit components. The component definitions may be selected for use in a device design. When a parametrization of a particular version of a discrete circuit component definition is changed, the version level of the device design is also changed and the circuit layout for the device design is physically verified for the new version level.

Abstract: An apparatus includes: a transmission line resonator; and multiple resonators coupled to the transmission line resonator, in which each resonator of the multiple resonators is coupled to the transmission line resonator at a different position X along a length of the transmission line resonator, and in which, for each resonator of the multiple resonators, a coupling position Y along a length of the resonator is selected such that, upon application of a source potential to the resonator, a standing wave established in the resonator is impedance and phase matched to a standing wave established in the transmission line resonator.
