For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other. Quantum theory governs particles and fields, while Einstein’s gravity describes ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...

Can a single particle have a temperature? It may seem impossible with our standard understanding of temperature, but ...

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 ...

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

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

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 ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Conventional wisdom has it that putting the ...
