a When photon-pair generation is probabilistic, a two-photon interference measurement between A2 and B1 alone cannot distinguish successful events from unsuccessful ones. Therefore, additional ...

“Einstein and Bohr would have never thought that this is possible, to perform such an experiment with single atoms and single photons,” said Wolfgang Ketterle, head of the MIT group whose new ...

Researchers are learning to flip light on and off one particle at a time, turning single photons into a controllable resource instead of a random byproduct of exotic materials. By engineering ...
