ALEXANDRIA, Va., June 19 -- United States Patent no. 12,332,973, issued on June 17, was assigned to INTERNATIONAL BUSINESS MACHINES Corp. (Armonk, N.Y.).

"Quantum state classifier using reservoir computing" was invented by Naoki Kanazawa (Yokohama, Japan).

According to the abstract* released by the U.S. Patent & Trademark Office: "A quantum state classifier includes a reservoir computing circuit for post-processing a quantum bit to obtain a readout signal, and a readout circuit, coupled to the reservoir computing circuit, for discriminating a quantum state of the quantum bit from the readout signal from among multiple possible quantum states. The readout circuit is trained in a calibration process respectively activated by a specific one ...
