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 ...

Physicists have performed a groundbreaking simulation they say sheds new light on an elusive phenomenon that could determine ...

New research explores the mechanics behind the "false vacuum" theory, the idea that the universe is in a state of only ...

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

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 ...

False vacuum decay model shows why our universe may be living on borrowed time In a nutshell Scientists used a 5,564-qubit ...

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 ...

The second law of thermodynamics, a cornerstone of modern physics, states that entropy—a measure of disorder—never spontaneously decreases. It governs everything from the efficiency of engines to the ...

The quantum and gravitational theory group works on a wide range of topics in theoretical physics, from string theory to quantum information, condensed matter, and cosmology.

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 ...

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