The 2022 Nobel Prize in Physics has been awarded to French scientist Alain Aspect, American scientist John F. Clauser and Austrian scientist Anton Zeilinger for “experiments with entangled photons, establishing violations of Bell’s inequality and pioneering quantum information science” “. John Clauser developed the inequality proposed by John Bell in the 1960s to conduct an actual quantum experiment. Alain Aspect developed this setting to switch measurement settings after an entangled pair leaves its source, so the settings that existed when they were fired did not affect the results. Through sophisticated tools and a series of experiments, Anton Zeilinger began working with entangled quantum states. His group also demonstrated a phenomenon known as quantum teleportation, which makes it possible for quantum states to move from one particle to another over a certain distance.
