How to balance quantum batteries' high power with stable energy delivery
Quantum batteries are an emerging area of research, with progress coming from theoretical studies and proof-of-principle experiments in small quantum systems.
AI Summary
Quantum batteries use quantum systems to store and transfer energy, differing from conventional chemical batteries. Researchers have mainly studied how quickly and powerfully these batteries can be charged. New work establishes fundamental limits on the fluctuations in both the energy delivered by a quantum battery and the rate at which that energy is delivered. The study provides theoretical bounds that could guide future designs of quantum batteries for processors and other quantum technologies.
