Abstract: A superconducting coupling device includes a resonator structure. The resonator structure has a first end configured to be coupled to a first device and a second end configured to be coupled to a second device. The device further includes an electron system coupled to the resonator structure, and a gate positioned proximal to a portion of the electron system. The electron system and the gate are configured to interrupt the resonator structure at one or more predetermined locations forming a switch. The gate is configured to receive a gate voltage and vary an inductance of the electron system based upon the gate voltage. The varying of the inductance induces the resonator structure to vary a strength of coupling between the first device and the second device.

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: Un dispositivo de acoplamiento superconductor incluye una estructura de resonador. La estructura de resonador tiene un primer extremo configurado para acoplarse a un primer dispositivo y un segundo extremo configurado para acoplarse a un segundo dispositivo. El dispositivo incluye además un sistema de electrones acoplado a la estructura de resonador y una compuerta colocada proximal a una porción del sistema de electrones. El sistema de electrones y la compuerta se configuran para interrumpir la estructura de resonador en una o más ubicaciones predeterminadas formando un conmutador. La puerta se configura para recibir un voltaje de compuerta y variar una inductancia del sistema de electrones con base en el voltaje de compuerta. La variación de la inductancia induce que la estructura de resonador varíe la fuerza de acoplamiento entre el primer dispositivo y el segundo dispositivo.

Abstract: A method for validation and runtime estimation of a quantum algorithm includes receiving a quantum algorithm and simulating the quantum algorithm, the quantum algorithm forming a set of quantum gates. The method further includes analyzing a first set of parameters of the set of quantum gates and analyzing a second set of parameters of a set of qubits performing the set of quantum gates. The method further includes transforming, in response to determining at least one of the first set of parameters or the second set of parameters meets an acceptability criterion, the quantum algorithm into a second set of quantum gates.

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.
