Quantum batteries, chips and computers: quantum technology in 2026
Quantum technologies exploit superposition, entanglement and other effects of quantum mechanics to perform tasks that classical physics cannot. After decades of theoretical development, 2026 produced milestones in two very different areas: energy storage and computing.
Quantum batteries: from theory to prototype
The idea of a quantum battery was formalised in 2013 by Robert Alicki and Mark Fannes, who showed that collective quantum operations could extract more work from a system than independent operations. Later theory predicted superabsorption: when many quantum systems interact collectively with light, the charging rate grows faster than the number of units, so a larger battery charges faster.
In March 2026, researchers from Australia's national science agency CSIRO, RMIT University and the University of Melbourne presented a proof-of-concept quantum battery in Light: Science & Applications. The device is a layered organic microcavity that is charged wirelessly by a laser, stores the energy and releases it, all at room temperature. It demonstrated the predicted collective effect: charging speed increased with the size of the device (RMIT, 2026). The research team identified extending the storage time as the next step and is seeking development partners. In parallel, groups in China and Spain have demonstrated a superconducting quantum battery using 12 qubits (Battery Technology, 2026).
Quantum computing reaches advantage
Quantum computers process information in qubits, which can exist in superpositions of 0 and 1. Their power grows with the number of high-quality qubits, but qubits are fragile, so practical machines need quantum error correction, which combines many physical qubits into more reliable logical qubits.
- IBM reported in July 2026 a demonstration with the University of Chicago that it describes as meeting the criteria for quantum advantage: solving a problem better than classical methods, with verifiable results (IBM, 2026). Its Nighthawk processor connects 120 qubits with 218 tunable couplers, and its roadmap targets a large-scale, fault-tolerant system by 2029.
- Google's 105-qubit Willow chip demonstrated error rates that fall as more qubits are added, a key threshold for scalable error correction, and ran the verifiable "Quantum Echoes" algorithm.
- Amazon Web Services introduced Ocelot, a chip based on "cat qubits" designed to reduce error-correction overhead by up to 90%.
Applications
- Energy: fast-charging storage for devices, sensors and vehicles.
- Medicine and chemistry: simulation of molecules for drug discovery and new materials.
- Electronics and communications: quantum sensors, secure communication and quantum-ready devices.
- AI: hybrid quantum-classical algorithms for optimisation and machine learning.
