Quantum physics just delivered a full-circle moment a century in the making. A team of researchers at University of Science and Technology of China (USTC) has reconstructed one of Albert Einstein’s ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to disprove the quantum mechanical principle of complementarity put forth by ...

In the 1920s, Albert Einstein proposed a twist on the double-slit experiment. Rather than a wall with two fixed slits, he imagined a very light slit that would recoil when a single photon passed ...
