ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,704,764, issued on Aug. 11, was assigned to ColdQuanta Inc. (Boulder, Colo.).
"Quantum-state readout using four-wave mixing" was invented by Alexander Georgiyevich Radnaev (Boulder, Colo.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Quantum state readout is achieved using four-wave mixing. A quantum-state carrier, e.g., a cesium 133 atom, is illuminated with a set of three wavelengths. In the event that the atom is in a first quantum state, e.g., an F=3 state of cesium 133, the illumination triggers emission in a first direction from the atom of a fourth wavelength due to four-wave mixing. Detection of the emission in the first direction thus indicate...
