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 ...

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 ...

demonstrating the digital quantum simulation of quantum field theory for curved spacetime (QFTCS). While attempts to create a ...

Complex Langevin Dynamics is an innovative approach in quantum field theory (QFT) that addresses significant computational challenges, particularly the notorious "sign problem." This problem ...

Pioneering research in quantum field theory around 50 years ago proposed that the universe may be trapped in a false vacuum – meaning it appears stable but in fact could be on the verge of ...

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 ...

demonstrating the digital quantum simulation of quantum field theory for curved spacetime (QFTCS). Researchers from Nagoya University in Japan and the Slovak Academy of Sciences have unveiled new ...

The breakthrough comes in the form of a new family of Quantum Low-Density Parity Check (QLDPC) codes that Photonic is calling ...

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

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 ...
