Nearly half a century ago, physicists proposed that the universe might be trapped in a metastable state known as a false vacuum. This state appears stable but could, over immense timescales, ...

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 ...

Scientists have used quantum computers to simulate how particles can appear in an expanding universe. This study, published ...

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 ...

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

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 ...

While the opportunities for quantum computing in life sciences are immense, it faces major challenges that must be addressed.

Researchers from Nagoya University in Japan and the Slovak Academy of Sciences discovered that quantum theory doesn’t forbid ...

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 ...
