How to build a particle collider the size of the solar system. To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could ...

In an attempt to speed up quantum measurements, a new Physical Review Letters study proposes a space-time trade-off scheme that could be highly beneficial for quantum computing applications.

Most modern quantum computers need to be cooled and vacuum-sealed to protect qubits with special properties. At Oak Ridge ...

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 — ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

Researchers from the University of Arizona, working with an international team, have captured and controlled quantum ...

Physicists of the 19th century assumed that space was distinct from time – and two researchers now suspect they were correct to do so. Their conclusion, which comes from considering the behaviour of ...
