Physicists have built a quantum gas that behaves nothing like the substances we are used to, and that is exactly why it is ...

For more than a decade, scientists have been investigating ways to develop a “quantum battery” that stores energy using photons rather than electrons or ions. While quantum batteries—thanks to ...

A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein's classical concept of spacetime has been announced in two papers published simultaneously by UCL ...

Classical and quantum mechanics don’t really get along as the science of the subatomic can get, well, weird. Take, for instance, quantum entanglement, which says that the state of one particle can be ...

Over the past decades, the mathematical formulation of physical theories has evolved to provide a unified framework that bridges classical mechanics, quantum mechanics and quantum information theory.

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

Fundamental physics faces a stubborn paradox: the current impossibility of reconciling the rules of the quantum world with those of gravity, despite a century of efforts. This theoretical divergence ...

Imagine using your cell phone to control the activity of your own cells to treat injuries and diseases. It sounds like something from the imagination of an overly optimistic science fiction writer.

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 ...
