Quantum Brilliance, a joint Australian-German company, has reported new advances in the development of applied quantum systems. Their main advantage is their ability to operate at room temperatures with minimal energy consumption. This is not yet a full-fledged quantum computer, but Quantum Brilliance says that it is not necessary to create one - they have chosen a different approach. The Australian scientists' developments are based on a long-established technology for building qubits on synthetic diamonds. The strict internal structure of such materials allows them to maintain the required qubit stability without cryogenic systems and magnetic fields. Quantum Brilliance engineers are credited with developing the interface elements for working with such qubits, as well as methods for scaling the architecture.
The current goal is 5 diamond qubits in a bundle, but to have full-scale computing you need at least ten times that number, which is what the Australians hope to achieve by 2025. In another five years they hope to release a quantum system on a chip, which will form the basis of future general purpose systems. For example, it will be quite feasible to add quantum modules in mobile gadgets.
The disadvantage of this technology has exactly one - in the current version, it has no practical application, but it is not hidden. Quantum Brilliance is focused specifically on miniaturization and the development of quantum systems as such. It is assumed that they will eventually take the form of a generic module, like a video card in modern computers, to which specific data will be transferred for targeted computations. Time will tell what their architecture and algorithms will be.
