CSIRO team demonstrates working quantum battery prototype with femtosecond charging

Researchers led by CSIRO's James Quach built a quantum battery prototype that charges in femtoseconds using a phenomenon called superabsorption, where organic dye molecules packed between two mirrors respond collectively to laser light. Unlike conventional batteries, this device charges faster as more molecules are added, and the team successfully extracted a small electrical current from it, extending earlier 2022 research that only showed rapid energy absorption.

Researchers Build Quantum Battery That Charges Faster With More Molecules

Scientists led by James Quach have demonstrated a quantum battery that exploits 'superabsorption,' a collective quantum effect where molecules synchronize their energy absorption rather than acting independently. This causes the charging rate to increase as more molecules are added, defying the classical expectation that each unit absorbs energy at a fixed, independent rate.
