Quantum batteries charge quickly but easily lose energy. In a new study, scientists used two sources of wave coherence — inside the charger and in a specially "squeezed" environment. Their combined effect creates a dark state that locks in energy, making the battery immune to leaks.

A quantum system can act as an ultra-sensitive sensor, but its ultimate precision used to be calculated by fully reconstructing all properties — a laborious process. Now scientists have shown that a few simple measurements suffice: a machine learning algorithm predicts precision based on particle co
