Single-Photon Experiment Confirms Feynman's Path-Integral Postulates After 78 Years

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.
