Advanced quantum technology needs integrated cryogenic control. Professor David Reilly and colleagues at the University of Sydney present in Nature a control platform that will allow the scale up of quantum tech to build useful machines. The platform can also be applied for use in data centres and other advanced electronics.

Quantum computers can solve extraordinarily complex problems, unlocking new possibilities in fields such as drug development, encryption, AI, and logistics. Now, researchers at Chalmers University of Technology in Sweden have developed a highly efficient amplifier that activates only when reading information from qubits. Thanks to its smart design, it consumes just one-tenth of the power consumed by the best amplifiers available today. This reduces qubit decoherence and lays the foundation for more powerful quantum computers with significantly more qubits and enhanced performance.

This work marks the first practical use of boson sampling, long seen as a key demonstration of quantum computing’s potential to outperform classical methods.

The researchers used computer simulations to model a quantum optical experiment that recognizes images using just three photons, successfully identifying images from several well-known datasets.

This paves the way towards future applications of quantum AI in complex image recognition, and represents a step toward low-resource, energy-efficient quantum computing.

Aston University biostatistician Dr Dan Green has identified the top ten errors he commonly sees in research papers in his work as a statistical reviewer for scientific and medical journals.

The BMFTR-funded SPINNING project has successfully demonstrated that hybrid-integrable, scalable, and near-room-temperature solid-state quantum components represent a robust and energy-efficient alternative to established quantum computing hardware platforms. The developed spin qubits in diamond outperform comparable commercially available superconducting systems in terms of longer operation times and lower error rates. Photonic coupling over distances of more than 20 meters promises to serve as a foundation for more powerful distributed quantum computers.
