US Patent Issued to Beijing Academy of Quantum Information Sciences on March 25 for "Spin state readout device of quantum sensor and spin state readout method" (Chinese Inventors)

ALEXANDRIA, Va., March 26 -- United States Patent no. 12,259,448, issued on March 25, was assigned to Beijing Academy of Quantum Information Sciences (Beijing).

"Spin state readout device of quantum sensor and spin state readout method" was invented by Yan Liu (Beijing) and Renfu Yang (Beijing).

According to the abstract* released by the U.S. Patent & Trademark Office: "A spin state readout device of a quantum sensor. The quantum sensor has spin-manipulable electrons. The spin state readout device includes: a pumping unit configured to emit a first laser to the quantum sensor to polarize the electron spin state of the quantum sensor; a probing unit configured to emit a second laser to the quantum sensor to make the spin-polarized quantum ...
