In holographic theories, physicists may have traced the pliability of space-time to its quantum roots: a measure of ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...

Theoretical physicists studying quantum fields in curved spacetime have built a growing body of calculations showing that ...

What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time ...

Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure communication at scale, and to connect ...

Bell's theorem, the well-known theoretical framework introduced by John Bell decades ago, delineates the limits of classical physical processes arising from relativistic causality principles. These ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

Quantum field dynamics in curved spacetime addresses how quantum fields—fundamental entities underpinning matter and forces—behave in the presence of gravitational curvature. Unlike flat Minkowski ...
