Quantum Brilliance‘ installation at the Pawsey Supercomputing Centre will initially be with a small two qubit device to be used as a field test to test out device integration with a classical supercomputer in a hybrid classical/quantum environment. The software platform used to program it will be the XACC (eXtreme scale ACCelerator) software framework originally developed at Oak Ridge National Laboratory. The company plans on scaling up the installation to larger systems as these basic integration and programming technologies mature.
Quantum Brilliance is one of the few companies pursuing a NV (Nitrogen Vacancy) diamond technologies to create qubits. This method embeds nitrogen atoms along with an empty adjacent site within a carbon diamond lattice. This NV center can be forced into a spin-up, spin-down, or a superposition of those states by light and microwave signals to control the state of the qubit. The technology can have significant advantages over other qubit implementation technologies because it can run at room temperature and provide high quality, stable qubits that are less affected by environmental noise. The historical challenge with NV diamond technology has been the difficulty in scaling it up to higher numbers of qubits. Quantum Brilliance is working on a new method for fabricating these devices using proprietary atomic scale fabrication techniques that they believe will overcome the scaling problems. Their longer term goal is to develop a processor containing 50+ qubits within five years that would be roughly the size of a graphics accelerator card. Because their technology does not require a dilution refrigerator and can be quite small, they believe they can serve many markets, including edge computing and mobile devices, that would not be practical with other technologies.
