Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

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 ...

In the future, quantum computers are anticipated to solve problems once thought unsolvable, from predicting the course of ...

"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, ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Light’s dual nature, manifesting as both wave-like and particle-like behaviour, is a phenomenon known as wave-particle duality and remains one of the most perplexing mysteries in quantum mechanics.

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

image: Artist's impression, inspired by the work of the artist Maurits Cornelis Escher, of the continuous morphing between particle- and wave-like behavior of light achieved in the Bristol experiment.

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 ...

Researchers have used a 350-year-old theorem to better understand the strange nature of light. The team took a theorem used for describing pendulums and substituted the brightness of light in for what ...
