A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out. But new in the way they share ...

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

In a paper published in Nature Photonics, the research team from the Center for Quantum Information and Communication – Ecole polytechnique de Bruxelles of Université libre de Bruxelles, has found an ...

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 ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...
