US EditionQuantum Battery Prototype Paves The Way For Almost-Instant Charging
The prototype exploits collective quantum effects to charge faster as it scales, storing energy briefly with potential use in powering quantum computers, researchers said.
- CSIRO and collaborators built the world's first prototype quantum battery with a metal 'sandwich' microcavity device that supports laser wireless charging and extracts energy as electrical current, reported in Light: Science & Applications.
- As background, the idea dating to 2013, the quantum battery concept remained theoretical until experimental efforts began in 2018 and a 2022 prototype with UK and Italy collaborators used an organic microcavity design.
- Crucially, collective quantum effects make charging time scale down as 1/N, and spectroscopy confirmed the microcavity 'sandwich' stored energy six orders of magnitude longer.
- However, the prototype's limits include a capacity of a few billion electron-volts and charge duration of a few nanoseconds, so the research team led by James Quach plans scaling and longevity improvements.
- Looking ahead, the technology could power quantum devices and help scale quantum computers, with Andrew White calling it a notable proof-of-concept validation for the field.

World's first quantum battery is well within reach
You’re late for an important appointment. Just as you are leaving your house, you realize your phone is flat. Imagine you could charge it almost instantly by exploiting the strange rules of quantum physics. That’s the promise of quantum batteries. My colleagues and I at CSIRO have developed the world’s first quantum battery prototypes – […] The post World’s first quantum battery is well within reach appeared first on Asia Times.
Quantum battery is no longer just science fiction. Australian researchers have unveiled the first functional prototype of a quantum battery that can charge, store and download energy. The study "Superextensive electric energy of a quantum battery" is quite extensive and technical, and can be read here. The Guardian and Tekniikan Maailma reported on the subject. Unlike traditional batteries, which are based on chemical reactions, quantum batterie…
