US Patent Issued to Google on May 13 for "Preparing superpositions of computational basis states on a quantum computer" (California Inventors)

ALEXANDRIA, Va., June 12 -- United States Patent no. 12,299,538, issued on May 13, was assigned to Google LLC (Mountain View, Calif.).

"Preparing superpositions of computational basis states on a quantum computer" was invented by Zhang Jiang (El Segundo, Calif.) and Ryan Babbush (Venice, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Methods, systems and apparatus for preparing arbitrary superposition quantum states of a quantum register on a quantum computer, the quantum state comprising a superposition of L computational basis states. In one aspect, a register of log L qubits is prepared in a weighted sum of register basis states, where each register basis state indexes a corresponding quantum state...
