In simpler terms, the second law of thermodynamics means that things naturally tend to become more disordered over time.

An international collaboration sheds new light on the relationship between quantum theory and thermodynamics. The research group demonstrated that while the laws of quantum theory alone do not ...

The difficulty – and, for physicists, the fun – starts here. To begin with, there’s no single quantum theory. There’s quantum mechanics, the basic mathematical framework that underpins it ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...

This is what is known as “quantum nonlocality,” where objects are influenced across distances (seeming beyond the speed of light) whereas classical physics follows local theory, the idea that ...

Today, it might be turning your computer off and on again. Quantum mechanics — the most successful and important theory in modern physics — is like that. It works wonderfully, explaining ...

It is a basic principle of quantum theory: sometimes certain physical quantities ... This means that a further class of states must now be taken into account when categorizing solids.
