A new study published in Scientific Reports simulates particle creation in an expanding universe using IBM quantum computers, ...

But for all its successes, quantum field theory has its own puzzles. Infamously, a straightforward calculation of the quantum corrections to the scattering probability of two particles often ...

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 ...

In their new book, From Spinors to Supersymmetry, Herbi Dreiner, Howard Haber and Stephen Martin describe the two-component formalism of spinors and its applications to particle physics, quantum field ...

Albert Einstein’s special theory of relativity, which explains what happens when things move very fast – to create what are known as quantum field theories. Three different quantum field ...

Quantum physics is the study of matter and energy at its most fundamental level. A central tenet of quantum physics is that energy comes in indivisible packets called quanta. Quanta behave very ...
