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.
The first functional quantum battery marks a turning point for energy technology by demonstrating, in practice, that these systems can be charged faster as they grow in size. The advance reinforces one of the most ambitious promises in the quantum field and opens the door to future applications, from portable devices to large-scale energy storage. *** The practical demonstration validates that a quantum battery can accelerate its charge by growi…
