ALEXANDRIA, Va., Sept. 23 -- United States Patent no. 12,422,732, issued on Sept. 23, was assigned to Washington University (St. Louis).
"Two-photon quantum photonic logic gates" was invented by Jung-Tsung Shen (St. Louis), Yao Zhou (St. Louis) and Zihao Chen (St. Louis).
According to the abstract* released by the U.S. Patent & Trademark Office: "Photonic controlled-phase gates that include a dipole emitter chirally coupled to a plurality of photonic qubit pairs in a waveguide are disclosed herein. Each photonic qubit pair includes a two-qubit state |xy, wherein the two-qubit state |xy comprises a combination of single-qubit states |0 and |1, and may be |00, |01, |10, and |11. The dipole emitter is configured to interact with the single-q...
