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 — ...

Space and time seem like two completely different ideas, but Einstein showed they are interlinked in what is known as ...

One of the greatest challenges of modern physics is to find a coherent method for describing phenomena, on the cosmic and microscale. For over a hundred years, to describe reality on a cosmic scale we ...

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 ...

The theory of relativity works well when you want to explain cosmic-scale phenomena – such as the gravitational waves created when black holes collide. Quantum theory works well when describing ...
