A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

Complementarity A principle proposed by Bohr in the mid-1920s, which argues that some pairs of physical properties, e.g. position and momentum of a particle, cannot be measured simultaneously ...

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is still the star of that show. A new, ultra-clean version of this classic test ...
