Quantum physics just took a leap from theory to reality! Empa researchers have, for the first time, successfully built a long ...

It was a product of what is now labelled the old quantum theory — a period of ad hoc theorizing between 1900 and 1925 that led to the introduction of a consistent theory of quantum mechanics in ...

What makes something quantum? This question has kept a small ... and Nobel laureate Hendrik Lorentz criticized the spin ...

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 ...

The breakthrough has reinvigorated an old and fundamental scientific ... More information: Berislav Buča, Unified Theory of ...

In 1927, Werner Heisenberg was in Denmark working at Niels Bohr's research institute in Copenhagen. The two scientists worked closely on theoretical investigations into quantum theory and the ...

This innovative approach uses quantum relative entropy, a concept from quantum information theory, to describe the interplay between spacetime geometry and matter. The study introduces a new ...
