US Patent Issued to INTERNATIONAL BUSINESS MACHINES on Aug. 18 for "Optimal qubit routing using double stochastic matrices" (Irish Inventors)

ALEXANDRIA, Va., Aug. 18 -- United States Patent no. 12,711,289, issued on Aug. 18, was assigned to INTERNATIONAL BUSINESS MACHINES Corp. (Armonk, N.Y.).

"Optimal qubit routing using double stochastic matrices" was invented by Nicola Mariella (Dublin) and Sergiy Zhuk (Dublin).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method for building a quantum computing circuit optimizes qubit routing in the circuit. A computer processor receives a plurality of qubits and an initial input circuit layer. Layers of quantum sub-circuits are extracted from the initial input circuit layer. Adjacency matrices are built for the layers of quantum sub-circuits. A cost function is determined for the extracted layers, based on...
