"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two centuries, the double-slit experiment has been providing a direct visual ...

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 ...

The first real-time movie of large molecules creating an interference pattern after passing through two slits has been made by an international team of physicists. As well as being a beautiful example ...

Road less travelled: a photon weaves its way through three slits A flaw in how quantum-interference experiments are interpreted has been quantified for the first time by a team of physicists in India.

The experiment, which the English physicist Thomas Young first conducted in 1800, is essentially quite simple: light passes through two thin parallel slits and is projected onto a screen. Because the ...
