ALEXANDRIA, Va., April 9 -- United States Patent no. 12,273,149, issued on April 8, was assigned to ColdQuanta Inc. (Boulder, Colo.).

"Radio-frequency receiver pumped to high-azimuthal Rydberg states" was invented by Seth Charles Caliga (Lafayette, Colo.), Haoquan Fan (Erie, Colo.) and Eric Magnuson Bottomley (Broomfield, Colo.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A radio-frequency receiver achieves high sensitivity by pumping atoms to high-azimuthal (less than=3) Rydberg states. A vapor cell contains quantum particles (e.g., cesium atoms). A laser system provides probe, dressing, and coupling beams to pump the quantum particles to a first Rydberg state having a high-azimuthal quantum number less t...
