Abstract: An analog computing system having a qubit which is provided with inductors positioned near to the qubit's Josephson junctions and inductors positioned far from the qubit's Josephson junctions. The near inductors exhibit capacitance-reducing behavior and the far inductors exhibit capacitance-increasing behavior as their respective inductances are increased. Near and far inductors can be tuned to homogenize the capacitance of the qubit across a range of programmable states based on predicted and target capacitance for the qubit. The inductors may be tuned to homogenize both capacitance and inductance.

Abstract: A hybrid processor includes a classical (digital) processor and a quantum processor and implements a calibration procedure to calibrate devices in the quantum processor. Parameter measurements are defined as vertices in a directed acyclic graph. Dependencies between measurements are defined as directed edges between vertices. The calibration procedure orders the vertices, respecting the order of the dependencies while at least attempting to reduce the time needed to perform all the measurements. The calibration procedure provides a level of abstraction to allow non-expert users to use the calibration procedure. Each vertex has a set of attributes defining the status of the measurement, time of the measurement and value of the measurement.

Abstract: Generate an automorphism of the problem graph, determine an embedding of the automorphism to the hardware graph and modify the embedding of the problem graph into the hardware graph to correspond to the embedding of the automorphism to the hardware graph. Determine an upper-bound on the required chain strength. Calibrate and record properties of the component of a quantum processor with a digital processor, query the digital processor for a range of properties. Generate a bit mask and change the sign of the bias of individual qubits according to the bit mask before submitting a problem to a quantum processor, apply the same bit mask to the bit result. Generate a second set of parameters of a quantum processor from a first set of parameters via a genetic algorithm.

Abstract: The systems, devices, articles, and methods described herein generally relate to analog computers, for example quantum processors comprising qubits, couplers, and, or cavities. Analog computers, for example quantum processor based computers, are the subject of various sources of error which can hinder operation, potentially reducing computational accuracy and speed. Sources of error can be broadly characterized, for example as i) a background susceptibility do to inherently characteristics of the circuitry design, ii) as an h/J ratio imbalance, iii) bit flip errors, iv) fidelity, and v) Anderson localization, and various combinations of the aforesaid.

Abstract: Systems and methods for fabricating a superconducting integrated circuit that includes wiring layers comprising low-noise material are described. A superconducting integrated circuit can be implemented in a computing system that includes a quantum processor. Such a superconducting integrated circuit includes a first set of one or more wiring layers that form a noise-susceptible superconducting device that can decrease processor when exposed to noise. The superconducting integrated circuit can further include a second set of one or more wiring layers that form a superconducting device that is less susceptible to noise. Fabricating a superconducting device that contains low-noise material can include depositing and patterning a wiring layer comprising a first material that is superconductive in a respective range of temperatures and depositing and patterning a different wiring layer comprising a second material that is superconductive in a respective range of temperatures. The second material can be considered a low-noise material.
