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 ...

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 ...

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

From the mid-1980s, string theory set up a possible framework to approach quantum gravity using a 'top-down' approach. The effective field theory approach to strong forces drove the development of ...

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 ...

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.
