Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have ...

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more ...

For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum ...

The famous double-slit experiment brings into question the very nature of matter. Its cousin, the quantum eraser experiment, ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

Hoboken, N.J., July 14, 2025 — 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 ...

Quantum gravity challenges the classical notion of spacetime by positing that the smooth, continuous fabric described by general relativity may arise from more fundamental, non-spatiotemporal entities ...

If spacetime is classical, it should undergo random fluctuations, which could in turn change the mass of objects by tiny amounts over time. One experiment the team suggests is that measuring an object ...

The field of quantum deformations explores systematic modifications of classical symmetry algebras that underpin our understanding of spacetime. These deformations introduce a quantum parameter – ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...

TU Wien researchers have uncovered a quantum twist to the paths particles take through spacetime — one that could finally ...
