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

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

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

[Stoppi] has taken on a fascinating project involving the interference of thin layers, a phenomenon often observed in everyday life but rarely explored in such depth. This project delves into the ...

Researchers have demonstrated that a nanoparticle of 7,000 sodium atoms can act as a wave, creating a record-setting ...

For more than a century, scientists have known that waves can behave in ways that seem to defy common sense, from freak walls ...

A sensitive matter-wave interferometer measuring moiré fringes offers force sensitivity comparable to quantum interference ...

Complementarity A new twist on the double-slit experiment. (Courtesy: Shutterstock/Andrey VP) One of the most counterintuitive concepts in physics – the idea that quantum objects are complementary, ...

The film "Introduction to Holography" explains the principles of holography, focusing on how it differs from traditional photography by creating three-dimensional images. It discusses the role of wave ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
