Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in ...

Quantum field theory (QFT) provides a comprehensive framework for describing the fundamental interactions of matter and radiation. In the context of atom‐field interactions, QFT elucidates how atoms ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other ...

A theoretical study suggests that gravity could have quantum effects without itself being a quantum theory. Other researchers ...

Quantum researchers in the twenty-first century are part of an international network that requires a great deal of ...

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 ...

Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether in a physics class, in the lab, or in popular science writing, is left ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Google's Willow quantum chip has achieved a significant breakthrough, performing calculations exponentially faster than ...

Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...
