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 ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

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

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 ...

Quantum theory has been remarkably successful ever since its inception 100 years ago. And yet, there is a glaring mismatch between the discrete, quantum nature of matter and the apparent continuous, ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

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 ...
