  • Patent number: 11704588
    Abstract: Apparatus and method for injected spin echo sequences in a quantum processor. For example, one embodiment of a processor includes a decoder to decode quantum instructions to generate quantum microoperations (uops) and to decode non-quantum instructions to generate non-quantum uops, execution circuitry to execute the quantum uops and non-quantum uops, and a corrective sequence data structure to identify and/or store corrective sets of uops for one or more of the quantum instructions. The decoder is to query the corrective sequence data structure upon receiving a first quantum instruction to determine if one or more corrective uops exist, and if the one or more corrective uops exist, the decoder is to submit the one or more corrective uops for execution by the execution circuitry.

  • Publication number: 20230016817
    Abstract: Apparatus and method for actively mitigating coherent errors by modifying an original quantum circuit, inserting Clifford gate operations at intermediate stages. Embodiments of the apparatus and method may perform CGI statically, at the compiling stage, and/or dynamically, at the control processing stage. The insertion of Clifford gates takes advantage of the symmetries in a quantum circuit and actively cancels coherent errors, maintaining the quantum processor in a state as close as possible to the original tune-up environment.
