Patent number: 11941490Abstract: Techniques regarding quantum computer error mitigation are provided. For example, one or more embodiments described herein can comprise a system, which can comprise a memory that can store computer executable components. The system can also comprise a processor, operably coupled to the memory, and that can execute the computer executable components stored in the memory. The computer executable components can comprise an error mitigation component that interpolates a gate parameter associated with a target stretch factor from a reference model that includes reference gate parameters for a quantum gate calibrated at a plurality of reference stretch factors.Type: GrantFiled: February 22, 2022Date of Patent: March 26, 2024Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Daniel Josef Egger, Don Greenberg, Douglas Templeton McClure, III, Sarah Elizabeth Sheldon, Youngseok Kim

Publication number: 20220292381Abstract: Techniques for quantum entanglement forging for quantum simulations are presented. A decomposer component can decompose a weakly entangled variational state into respective local components of the weakly entangled variational state, wherein the respective local components describe respective tensor product states. A quantum computing simulator component can perform respective quantum simulations of the respective local components of the weakly entangled variational state, and can determine respective portions of variational energy contributed by the respective tensor product states associated with the respective local components based on the respective quantum simulations of the respective local components of the weakly entangled variational state. An energy determination component can determine a variational energy associated with the weakly entangled variational state based on the respective portions of the variational energy contributed by the respective tensor product states.Type: ApplicationFiled: March 12, 2021Publication date: September 15, 2022Inventors: Sergey Bravyi, Sarah Elizabeth Sheldon, Mario Motta, Antonio Mezzacapo, Tanvi Pradeep Gujarati, Andrew Eddins
