Jakarta, INTI - Scientists from Australia and Japan have proposed a new quantum computer design powered by a quantum battery, aimed at creating future computing systems that are faster, more reliable, and energy-efficient.
This groundbreaking study was published in the journal Physical Review X.
The research team demonstrated theoretically that an extremely small quantum battery can efficiently supply power to a quantum computer.
Energy Recycling and Power Reduction
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) stated that quantum batteries could increase the number of qubits up to four times in computing systems.
James Quach, the study’s author and head of quantum battery research at CSIRO, explained that the system enables significantly lower energy consumption. This is possible because the internal quantum battery can recycle energy within the system during operation.
“Quantum batteries are small but extremely powerful,” Quach said.
He also added that the technology brings quantum computing closer to solving challenges related to energy, cooling, and infrastructure.
The quantum battery functions as an internal “fuel tank” capable of recharging itself when integrated into the machine.
Greater Scaling Potential and Practical Development
Quantum computers operate based on quantum physics principles to solve complex problems, with the potential to transform sectors such as computing, medicine, energy, finance, and communications.
However, the need for large cryogenic cooling systems and room-temperature electronic components remains a major barrier to scaling this technology.
Quantum batteries, a type of energy storage device that uses light and can be recharged through light exposure, can be integrated directly into quantum computers.
“We have calculated that systems powered by quantum batteries will generate significantly less heat, require fewer wiring components, and be able to accommodate more qubits within the same physical space, all of which are important steps toward the development of practical and scalable quantum computers,” the research team explained.
Conclusion
The integration of quantum batteries into quantum computers offers a promising pathway toward faster, more efficient, and scalable quantum computing. By reducing heat, minimizing wiring, and enabling higher qubit density, this technology could overcome key practical and energy challenges, bringing the vision of deployable, large-scale quantum computers closer to reality.
