# Quantum batteries could quadruple qubit capacity while reducing energy infrastructure requirements

**[Phys.org](https://daily.dev/sources/phys)** · 3 min read · 0 upvotes · 0 comments

## Summary

Researchers from CSIRO, University of Queensland, and OIST have theoretically demonstrated that quantum batteries could power quantum computers, potentially quadrupling qubit capacity while significantly reducing energy and cooling requirements. These batteries store energy using light and can be recharged by the computer's own components through quantum entanglement. The approach could reduce heat generation, minimize wiring, and improve computational speed through quantum superextensivity. While still theoretical, this breakthrough addresses major barriers to scaling quantum computers.
