Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called asymptotic safety, thinks we just need to push a little further.

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

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 ...

A new computational simulation of the early universe has revealed a fundamental, unbreakable geometric limit to the fabric of spacetime, dubbed the "Metric Wall." Discovered by independent physics ...

However, to measure spacetime fluctuations with an interferometer, we need to know where—i.e. at what frequency—to look, and what the signal will look like. With our framework, we can now predict this ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

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 feels so obvious that time moves forward that questioning it can seem almost pointless.

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 — ...
