US Patent Issued to The American University in Cairo on May 12 for "Measurement-based cooling of quantum systems" (Egyptian Inventor)

ALEXANDRIA, Va., May 12 -- United States Patent no. 12,625,531, issued on May 12, was assigned to The American University in Cairo (New York).

"Measurement-based cooling of quantum systems" was invented by Tarek Ahmed Elsayed (Embaba, Egypt).

According to the abstract* released by the U.S. Patent & Trademark Office: "A technique is provided for cooling generic many-body quantum systems of unknown Hamiltonians to their ground states with a very high fidelity. The technique works by switching on a strong field and applying a sequence of projective measurements and RF pulses to polarize the system along the direction of the external field before we adiabatically switch the field off. The evolution of the system towards its ground state is go...
