A new optical fiber link between CERN and Paris will provide the Laboratory with an accurate frequency reference, enhancing ...

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 ...

demonstrating the digital quantum simulation of quantum field theory for curved spacetime (QFTCS). While attempts to create a complete quantum theory of gravity have been unsuccessful, there is ...

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 ...

Under quantum field theory, particles interact over zero distance in spacetime. Under the general theory of relativity, the theorized force carrier particle for gravity, the graviton, cannot ...

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 ...

I did my Ph.D. in Theoretical Physics, in the area of Quantum Field Theory, which strangely enough, works amazingly well in explaining the real world. The fact that nature seems to obey the rules ...

A collaborative team of researchers from the Max Planck Institute for Structure and Dynamics of Matter (MPSD), Nanjing ...

Quantum field theory's vacuum concept challenges classical views, revealing a metastable state that influences cosmic ...

Physicists have performed a groundbreaking simulation they say sheds new light on an elusive phenomenon that could determine the ultimate fate of the Universe. Physicists have performed a ...

Researchers have successfully simulated particle creation in an expanding universe using IBM's advanced quantum computers.
