ALEXANDRIA, Va., July 9 -- United States Patent no. 12,353,959, issued on July 8, was assigned to Google LLC (Mountain View, Calif.).
"Quantum error correction" was invented by Austin Greig Fowler (Reseda, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Methods, systems and apparatus for quantum error correction. A layered representation of error propagation through quantum error detection circuits is constructed. The layered representation includes multiple line circuit layers that each represent a probability of local detection events in a quantum computing system associated with potential error processes in an execution of a quantum algorithm. To construct the layered representation, potential detec...
