For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter ...

A team from UNIGE shows that it is possible to determine the state of a quantum system from indirect measurements when it is coupled to its environment.

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...

First experimental observation of matter-wave diffraction in a short-lived electronpositron atom using a graphene-based ...

For the first time, researchers from Tokyo University of Science have observed wave-like interference patterns from ...

A near-100-year-old debate between the theoretical physicists Albert Einstein and Niels Bohr has finally been settled—and not in the former’s favor. A team of physicists in China have realized a ...

Sorta sparked by this comment someone made to me but it's similar to what other people have told me before: I was listening to a lecture on quantum electrodynamics and it helped me conceptualize the ...

From the birth of quantum mechanics to the cutting edge of nanoscience and the deepest reaches of fundamental physics, this article explores how our understanding of the universe has evolved—from the ...

Photonics, the study and development of devices that use photons, has significantly shaped today’s technological landscape. Just as J.J. Thomson’s discovery of the electron laid the foundation for ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...
