Abstract: A quantum computer includes a quantum processor that includes a first plurality of qubits arranged in a hexagonal lattice pattern such that each is substantially located at a hexagon apex, and a second plurality of qubits each arranged substantially along a hexagon edge. Each of the first plurality of qubits is coupled to three nearest-neighbor qubits of the second plurality of qubits, and each of the second plurality of qubits is coupled to two nearest-neighbor qubits of the first plurality of qubits. Each of the second plurality of qubits is a control qubit at a control frequency. Each of the first plurality of qubits is a target qubit at one of a first target frequency or a second target frequency. The quantum computer includes an error correction device configured to operate on the hexagonal lattice pattern of the plurality of qubits so as to detect and correct data errors.

Abstract: On a first superconducting layer deposited on a first surface of a substrate, a first component of a resonator is pattered. On a second superconducting layer deposited on a second surface of the substrate, a second component of the resonator is patterned. The first surface and the second surface are disposed relative to each other in a non-co-planar disposition. In the substrate, a recess is created, the recess extending from the first superconducting layer to the second superconducting layer. On an inner surface of the recess, a third superconducting layer is deposited, the third superconducting layer forming a superconducting path between the first superconducting layer and the second superconducting layer. Excess material of the third superconducting layer is removed from the first surface and the second surface, forming a completed through-silicon via (TSV).

Abstract: A quantum computing device includes a first chip having a first substrate and one or more qubits disposed on the first substrate. Each of the one or more qubits has an associated resonance frequency. The quantum computing device further includes a second chip having a second substrate and at least one conductive surface disposed on the second substrate opposite the one or more qubits. The at least one conductive surface has at least one dimension configured to adjust the resonance frequency associated with at least one of the one or more qubits to a determined frequency adjustment value.

Abstract: Una computadora cuántica incluye un procesador cuántico que incluye una primera pluralidad de bits cuánticos arreglados en un patrón de cuadrícula hexagonal tal que cada uno se ubique sustancialmente en un ápice de hexágono, y una segunda pluralidad de bits cuánticos cada uno arreglado sustancialmente a lo largo de un borde de hexágono. Cada una de la primera pluralidad de bits cuánticos se acopla a tres bits cuánticos vecinos más cercanos de la segunda pluralidad de bits cuánticos, y cada una de la segunda pluralidad de bits cuánticos se acopla a dos bits cuánticos vecinos más cercanos de la primera pluralidad de bits cuánticos. Cada uno de la segunda pluralidad de bits cuánticos es un bit cuántico de control a una frecuencia de control. Cada uno de la primera pluralidad de bits cuánticos es un bit cuántico diana en una de una primera frecuencia diana o una segunda frecuencia diana. La computadora cuántica incluye un dispositivo de corrección de errores configurado para operar en el patrón de cuadrícula hexagonal de la pluralidad de bits cuánticos a fin de detectar y corregir errores de datos.
