ABSTRACT: We establish quantum circuit complexity as a fundamental physical observable and prove that it satisfies an uncertainty relation with energy, analogous to Heisenberg’s canonical uncertainty ...

Findings from the Dark Energy Spectroscopic Instrument (DESI) suggest that dark energy could be evolving over time. If ...

Dark matter has baffled physicists for nearly a century, quietly shaping our universe's unseen framework. Invisible yet ...

Last year, an enormous map of the cosmos hinted that the engine driving cosmic expansion might be sputtering. Now physicists ...

The issue of debate is artificial intelligence and whether AI will be smarter than human beings. Speculation about developments in machine learning and computat ...

Quantum physics just took a leap from theory to reality! Empa researchers have, for the first time, successfully built a long ...
