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

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

The Pauli exclusion principle is a cornerstone of the Standard Model of particle physics and is essential for the structure and stability of matter. Now an international collaboration of physicists ...

For nearly a century, some of the simplest questions in quantum theory have stubbornly resisted clean answers, turning basic ...

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

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

A real mind-melter: Quantum mechanics is strange, but even for a field of science that regularly defies our conventional understanding of reality, the latest discovery is particularly baffling.

Two African science journalists – Paul Adepoju and Mkhululi Chimoio – have won the “ Quantum Pitch Competition ”, organized by Physics World and Physics Magazine to mark the International Year of ...

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 ...
