US Patent Issued to University of Tartu on Dec. 2 for "Shift rule for gradient determination in parameterised quantum evolutions" (Estonian Inventor)

ALEXANDRIA, Va., Dec. 2 -- United States Patent no. 12,488,267, issued on Dec. 2, was assigned to University of Tartu (Tartu, Estonia).

"Shift rule for gradient determination in parameterised quantum evolutions" was invented by Dirk Oliver Theis (Tartu, Estonia).

According to the abstract* released by the U.S. Patent & Trademark Office: "A hybrid computing system configured to estimate a derivative of a parameter-dependent physical quantity that is dependent on a first control parameter Theta of a parameterised quantum evolution executed by the quantum computing system. The classical computing system determines, based on an input bounding value and phase-correction value, a subset multiset of shift-values which define an equivalent subset...
