US Patent Issued to The University of Chicago on April 15 for "Quantum spin amplification" (Illinois, Tennessee Inventors)

ALEXANDRIA, Va., June 5 -- United States Patent no. 12,276,710, issued on April 15, was assigned to The University of Chicago (Chicago).

"Quantum spin amplification" was invented by Aashish Clerk (Chicago), Martin Koppenhofer (Chicago) and Peter Groszkowski (Knoxville, Tenn.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method for quantum spin amplification includes spin-polarizing an ensemble of quantum spins in an initial spin state to generate a transversely-polarized sensing spin state. The quantum spins identically have an upper energy state and a lower energy state. The sensing spin state accumulates a phase shift that transforms the sensing spin state into a phase-accumulated spin state having firs...
