Patent number: 11494683Abstract: Josephson junctions (JJ) may replace primary inductance of transformers to realize galvanic coupling between qubits, advantageously reducing size. A long-range symmetric coupler may include a compound JJ (CJJ) positioned at least approximately at a half-way point along the coupler to advantageously provide a higher energy of a first excited state than that of an asymmetric long-range coupler. Quantum processors may include qubits and couplers with a non-stoquastic Hamiltonian to enhance multi-qubit tunneling during annealing. Qubits may include additional shunt capacitances, e.g., to increase overall quality of a total capacitance and improve quantum coherence. A sign and/or magnitude of an effective tunneling amplitude ?eff of a qubit characterized by a double-well potential energy may advantageously be tuned. Sign-tunable electrostatic coupling of qubits may be implemented, e.g., via resonators, and LC-circuits. YY couplings may be incorporated into a quantum anneaier (e.g., quantum processor).Type: GrantFiled: December 19, 2018Date of Patent: November 8, 2022Assignee: D-WAVE SYSTEMS INC.Inventors: Mohammad H.

Patent number: 11348024Abstract: A quantum processor is operable as a universal adiabatic quantum computing system. The quantum processor includes physical qubits, with at least a first and second communicative coupling available between pairs of qubits via an in-situ tunable superconducting capacitive coupler and an in-situ tunable superconducting inductive coupler, respectively. Tunable couplers provide diagonal and off-diagonal coupling. Compound Josephson junctions (CJJs) of the tunable couplers are responsive to a flux bias to tune a sign and magnitude of a sum of a capacitance of a fixed capacitor and a tunable capacitance which is mediated across a pair of coupling capacitors. The qubits may be hybrid qubits, operable in a flux regime or a charge regime. Qubits may include a pair of CJJs that interrupt a loop of material and which are separated by an island of superconducting material which is voltage biased with respect to a qubit body.Type: GrantFiled: July 6, 2018Date of Patent: May 31, 2022Assignee: D-WAVE SYSTEMS INC.Inventors: Richard G.

Publication number: 20050162302Abstract: A sub-flux quantum generator includes an N-turn ring having a plurality of connected turns about a common aperture. The width of each respective turn in the N-turn ring exceeds the London penetration depth of a superconducting material used to make the respective turn. The generator includes a switching device configured to introduce a reversible localized break in the superconductivity of at least one turn in the N-turn ring. The generator includes a magnetism device configured to generate a magnetic field within the aperture of the N-turn ring. A method for biasing a superconducting structure that encompasses all or a portion of an N-turn ring. While a supercurrent is flowing through the N-turn ring, a quantized magnetic flux is introduced into the aperture of the N-turn ring using a reversible localized break in a turn in the ring. The quantized magnetic flux is trapped in the ring by removal of the localized break. The trapped flux biases the superconducting structure.Type: ApplicationFiled: March 11, 2005Publication date: July 28, 2005Inventors: Alexander Omelyanchouk, Anatoly Smirnov

Publication number: 20050001209Abstract: A method for determining whether a first state of a quantum system is occupied is provided. A driving signal is applied to the system at a frequency corresponding to an energy level separation between a first and second state of the system. The system produces a readout frequency only when the first state is occupied.
