Physicists have long struggled with their goal of making gravity a quantum force. A radical post-quantum approach might solve ...

An international team of researchers has found a surprisingly simple relationship between the rates of energy and information transmission across an interface connecting two quantum field theories.

Physicists have confirmed the two foundational postulates of Richard Feynman’s path-integral approach to quantum mechanics in ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

An explanation of two key reasons why quantum gravity remains unsolved: the mathematical incompatibility between quantum theory and general relativity, and the extreme weakness of gravitational ...

At first glance, some scientific research can seem, well, impractical. When physicists began exploring the strange, subatomic world of quantum mechanics a century ago, they weren’t trying to build ...

Recently, I have had more opportunities to research time, light, quantum computers, and other topics for my note articles. As I did so, I noticed that I was encountering the same number in quite a few ...

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 ...

Simulating the fundamental forces of nature on a computer is one of the grand challenges of modern physics, and a team at the ...
