According to the studies of quantum mechanics, light can act simultaneously as a particle and a wave. However, scientists have never been able to capture light in both of its forms at the same time— ...

"These single atoms are like the smallest slits you could possibly build." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. For over 100 years, ...

Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...

Metal clusters made of thousands of atoms showed quantum interference, offering new insight into how large objects follow ...

Physicists use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves. Since the 17th century, when Isaac Newton and Christiaan Huygens ...

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

Artist's impression of single photons' behavior when passing through an interferometer having a quantum beam-splitter at its output. In the back of the picture, sinusoidal oscillations are observed, ...
