"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 ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

Exotic paths: artist's impression of the microwave triple-slot experiment. Courtesy: G Rengaraj et al/New Journal of Physics) The importance of including exotic “non-classical paths” in analyses of ...

Quantum physicists have found a way to let a single qubit experience several different “journeys” through time at once, effectively bending a classic limit on how fast quantum systems are allowed to ...

Far from being a solely quantum mechanical phenomenon, interference occurs with all kinds of waves, including water waves and sound waves. Interference is the process in which two or more waves of the ...

Three's company: interference patterns for one to four slits (expand for full image) A group of physicists in Austria has directed a beam of large molecules at a series of extremely narrow slits to ...

WASHINGTON — Researchers have designed and demonstrated two all-silicon terahertz metasurface devices that can be used to create four optical channels for simultaneously implementing different optical ...

The validity of the superposition principle and of Born’s rule are well-accepted tenants of quantum mechanics. Surprisingly, it has been predicted that the intensity pattern formed in a three-slit ...
