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 ...

Does quantum mechanics allow the future to retroactively influence the past, as in the infamous delayed choice quantum eraser ...

A glittering hunk of crystal gets its iridescence from a highly regular atomic structure. Frank Wilczek, the 2012 Nobel ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

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 ...

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 ...

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.

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 — ...
