The famous second law of thermodynamics says that the world gets more and more disordered when random chance is at play. Or, ...

Philip Ball looks at how a little-known paper by Niels Bohr demonstrates the turmoil in physics on the brink of quantum ...

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 ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet ...

Theoretical physicists have established a close connection between the two rapidly developing fields in theoretical physics, quantum information theory and non-invertible symmetries in particle ...

While the prevailing consensus has been that Einstein's theory of gravity must be modified to fit within the framework of quantum theory, a new theory, coined as a "postquantum theory of classical ...

Entropy always increases, but in quantum systems, traditional entropy measures seem constant. TU Wien researchers resolved this paradox by considering Shannon entropy, which accounts for the ...

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 ...

Quantum computing relies on quantum mechanics, a fundamental theory of physics that describes how the world works at the level of the atom and subatomic particles, to solve problems that ...

The chip has broken new ground in a key random circuit sampling benchmark, an important development in Google's roadmap for ...

But a team of physicists has now taken a significant step forward in validating string theory by using an innovative mathematical ... Physics: Current Generated by the Quantum Hall Effect Has ...
