Patent number: 11809962Abstract: Techniques for automating quantum circuit debugging are provided that simulate standard debugging behaviors. The technology includes rewriting a source quantum circuit into instrumented circuits based on instrumentation instruction information inserted into software code that corresponds to the source quantum circuit. The instrumented circuits can executed to obtain measurement data corresponding to different state data of qubits within the source quantum circuit. The measurement data can be processed to output generated information corresponding to one or more internal states or processes of a quantum computer associated with the source quantum circuit.Type: GrantFiled: November 22, 2021Date of Patent: November 7, 2023Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Lev Samuel Bishop, Andrew Cross, Jay Gambetta

Patent number: 10915831Abstract: Techniques facilitating reduction and/or mitigation of crosstalk in quantum bit gates of a quantum computing circuit are provided. A system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise a signal generation component that implements a control sequence that comprises a single pulse type for a first quantum bit and at least a second quantum bit of a quantum circuit. The computer-executable components can also comprise a coordination component that synchronizes a first pulse of a first channel of the first quantum bit and at least a second pulse of at least a second channel of the second quantum bit. The coordination component can simultaneously apply the first pulse to the first quantum bit and at least the second pulse to at least the second quantum bit.Type: GrantFiled: December 18, 2019Date of Patent: February 9, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Lev Samuel Bishop, Jay Gambetta

Patent number: 10467544Abstract: Various embodiments provide a coupling mechanism, method of activation and a square lattice. The coupling mechanism comprises two qubits and a tunable coupling qubit that activates an interaction between the two qubits by modulation of a frequency of the tunable coupling qubit. The tunable coupling qubit capacitively couples the two qubits. The tunable coupling qubit is modulated at a difference frequency of the two qubits. The difference frequency may be significantly larger than an anharmonicity of the two qubits. The tunable coupling qubit may be coupled to the two qubits by two electrodes separated by a superconducting quantum interference device (SQUID) loop having two Josephson junctions or by a single electrode with a SQUID loop coupling to ground. The SQUID loop is controlled by an inductively-coupled flux bias line positioned at the center of the tunable coupling qubit.Type: GrantFiled: December 31, 2015Date of Patent: November 5, 2019Assignee: International Business Machines CorporationInventors: Stefan Filipp, Jay Gambetta
