Physicists in China have directly measured the probability amplitudes of more than 1.4 million possible paths taken by single photons, validating both foundational postulates of Richard Feynman's 1948 path-integral formulation of quantum mechanics for the first time.
Single-Photon Experiment Confirms Feynman's Path-Integral Postulates After 78 Years
