Startup developed a quantum processor with a graphics card


The Australian-German startup Quantum Brilliance announced the creation of a quantum microprocessor, which can be placed in the body with a size with a regular graphics card. It works at room temperature and exceeds the performance of huge modern quantum supercomputers requiring cryogenic cooling. But this is not all — the company’s engineers are confident that they can still reduce their development that it will fit in a mobile device.

Modern quantum computers are huge and extremely sensitive machines. They must be isolated from everything that can disrupt the calculation. To do this, they are placed in vacuum chambers, where only several molecules remain on the cubometer, and surround the electromagnetic fields.

In addition, such machines require low temperature. Any atom warmer with absolute zero by definition is in a state of vibration, and the temperature above 10-15 thousand degrees above this mark prevents cubes to support coherence. Therefore, most quantum computers for correct operation requires complex cryogenic cooling equipment,

All these conditions do not too much correspond to the image of an affordable and portable quantum computer, but the startup Quantum Brilliance declared the development of a quantum microprocessor, which works perfectly at room temperature. While it is one rack size, but will soon decrease to a graphics card, and then it will be able to fit and inside the mobile device.

Quantum Brilliance quantum computer, judging by the technical documentation, from the array of processor nodes, each of which contains the so-called NV center (nitrogen-substituted vacancy in diamond) and a cluster of nuclear spins. The backs of the cores act as a computer cube, and the NV centers perform the role of transport for operations with a plurality of cubes. Quantum calculations are controlled by radio frequencies, microwaves, optical and magnetic fields.

«We use the fundamental property of a nuclear spin, not a spin of an electron,» explained Mark Mattinj Scott, head of the German branch of the company. — The atom is less sensitive to temperature fluctuations, for example, than an electron, so we can increase the temperature to room temperature. The NV center has a hole with which we can interact with cubes. There are a lot of interactions, so we get a few cubes per vacancy in the potential. «

Startup has already built several 5-cubic processors with a rack size, and in 2025 plans to enter the market with a «quantum accelerator» by 50 cubes. In about ten years, the developers hope to release the system on the chip for mobile devices.
