Researchers in Australia have built and tested what they call the world’s first working quantum battery — a tiny device that demonstrates the strange advantages quantum physics could bring to energy storage. The prototype doesn’t power a phone or car yet, but it proves a long-theorized idea can move off the whiteboard and into the lab, revealing both immense promise and major obstacles.
Charged remotely by a laser, the unit reached full charge in an almost incomprehensible fraction of a second. At the same time, its ability to hold and deliver energy remains far too short for practical use. The experiment gives scientists a concrete platform to refine designs that, if scaled and stabilized, might one day transform fast charging for electronics and electric vehicles.

The prototype was built and tested by researchers at CSIRO, Australia’s national science agency, with Dr. James Quach leading the team. The device demonstrates a complete charge-discharge cycle — a milestone for a concept that has existed mainly in theoretical work since about 2013.
Instead of conventional chemical reactions, this battery relies on quantum effects to store energy. A laser was used to wirelessly pump energy into the system, a method made possible by quantum interactions among the battery’s components. The charging event happened in a few quadrillionths of a second (on the order of femtoseconds), illustrating one of the most striking potential advantages of quantum battery designs: extraordinarily fast charging.
Key technical details
- Charging method: wireless laser excitation.
- Charge time: an ultrafast pulse measured in quadrillionths of a second.
- Discharge time: only a few nanoseconds — far too brief for practical devices.
- Voltage and energy capacity: currently very small; insufficient to power consumer electronics.
Why ultrafast charging is exciting — and why storage time still matters
One counterintuitive prediction of quantum battery theory is that as you increase the number of interacting quantum units, the system can charge more quickly — the larger the battery, the faster the collective charging can become. Dr. Quach highlighted this unusual scaling behavior as a major reason the research community is energized by early demonstrations.
However, the prototype’s rapid charging is balanced by a tiny storage window. The device loses its charge in a few nanoseconds, which is about six orders of magnitude slower than the charge time but still far too brief for everyday applications. To put the science in perspective:
- If a mobile phone charged in 30 minutes and then held its energy for only a few nanoseconds, it would be useless as a practical battery.
- Scaling up the technology and increasing the charge retention time are the two major engineering challenges before any real-world benefit can be realized.
Longer storage time is essential — for communications, transport, and consumer electronics, energy needs to remain available for seconds, minutes, or hours, not just nanoseconds. Current experiments provide a snapshot of the quantum behavior scientists want to control, but they also make clear how much needs to change.
Reaction from the scientific community and possible applications
Independent experts welcomed the milestone. Professor Andrew White from the University of Queensland told press outlets the experiment is a major step because it moves the idea from theoretical models into an actual working device. That shift opens the door for practical engineering work rather than purely mathematical debates.
Potential applications that researchers envision — if the technology can be improved — include:
- Near-instant charging for small devices, reducing downtime for phones and wearables.
- Very rapid top-up charging for electric vehicles, changing user expectations about refueling time.
- Specialized roles in quantum networks or sensors where short, high-intensity energy delivery is useful.
What must happen next: technical hurdles and research directions
Scientists list several areas that need progress before quantum batteries approach everyday utility:
- Increase energy retention: extend storage time from nanoseconds to seconds or longer.
- Boost capacity and voltage: raise the absolute amount of storable and deliverable energy.
- Scale the system: translate laboratory-scale quantum behavior into larger assemblies without losing the beneficial quantum effects.
- Stabilize and integrate: make devices robust enough for real-world environments and compatible with existing electronics and charging infrastructure.
Researchers are already exploring material designs, error suppression techniques, and new ways to couple quantum units so that charging speed and storage time can both improve. The CSIRO prototype is a proof of concept that changes the research conversation — from “can this work?” to “how can we make it useful?”
