Quantum coherence, a property of matter that separates the classical from the quantum world, is most clearly demonstrated in a double-slit experiment with single electrons 1. It is based on the ...

An international group of physicists has found a way of measuring both the position and the momentum of photons passing through the double-slit experiment, upending the idea that it is impossible to ...

The subtlest experiment in quantum mechanics is also one of the simplest: send a stream of particles through two openings in a barrier, and you’ll produce an interference pattern because the particles ...
