Overview

  • Researchers at RMIT University and CSIRO boosted quantum battery storage from nanoseconds to microseconds, marking a 1,000-fold improvement in discharge lifetime.
  • The extended retention was achieved by precisely aligning two specific quantum energy levels within microcavity devices.
  • RMIT and CSIRO are collaborating with industry partners to design next-generation prototypes based on the proof-of-concept devices.
  • A team at PSL Research University and the University of Pisa has introduced a solvable oscillator model that rigorously certifies quantum charging at the fundamental speed limit.
  • Together, these advances deepen understanding of quantum charging mechanisms and pave the way for future applications in solar efficiency and small-scale electronics.
