Quantum superposition or quantum entanglement concept illustration. Superposition is the ability of a quantum system to be in multiple states at the same time until it is measured. Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently.

Rethinking reality: Is the entire universe a single quantum object?

5 July 2023

In the face of new evidence, physicists are starting to view the cosmos not as made up of disparate layers, but as a quantum whole linked by entanglement

The CERN particle accelerator that will breathe new life into physics

21 February 2023

A new breed of collider, called plasma wakefield accelerators, can study fundamental physics in new ways by doing something the Large Hadron Collider cannot do: colliding electrons

Hints of a fifth force of nature may only interest researchers and science lovers for now, but physics breakthroughs have a habit of delivering technological leaps

Fabiola Gianotti on why science at CERN has no borders

27 July 2020

The particle physics discoveries have dried up but in politically uncertain times CERN's cooperative model is an example to the world, says its chief Fabiola Gianotti.

Antimatter

25 March 2020

The world we live in is overwhelmingly made up of particles of matter. But many of these particles have an antimatter equivalent: a particle identical in every respect, but with an opposite charge.

Quantum physics

15 May 2019

Quantum physics underlies how atoms work, and so why chemistry and biology work as they do. You, me and the gatepost – at some level at least, we’re all dancing to the quantum tune.
