Many of nature's most important processes depend on how particles of matter interact with light and other force-carrying particles. So far, however, it has proven difficult for conventional computers ...

A tiny machine made from just an atom and particles of light may sound impossibly simple, but it raises a surprisingly difficult question: what counts as heat, and what energy can still do useful work ...

Ever since quantum mechanics first described particles, like electrons, as rippling waves, researchers have wondered if those ...

Purdue University researcher Libai Huang is using an ultrafast microscopy technique to capture the movement and interactions ...

Scientists have achieved a quantum breakthrough by creating an ultra-clean surface where individual molecules can maintain ...
