Quantum Brilliance Partners with La Trobe University and RMIT University to Research Diamond Quan...

The three organizations have created a Research Hub for Diamond Quantum Materials to focus on atom-scale fabrication techniques for nitrogen-vacancy (NV) centers in diamond. Quantum Brilliance is developing quantum processors using what is called an NV diamond technology that involves implanting nitrogen ions into a crystalline diamond structure to create NV centers that form qubits based upon an electron's spin. There could be a major advantage in NV diamond technology because it can run at room temperature and provide long coherence times without requiring an expensive dilution refrigerator. The trick is to obtain precise fabrication of arrays of NV centers that are separated by a few nanometers so that multi-qubit operations can be performed reliably. Previous techniques for fabricating these structures have not been good enough, but Quantum Brilliance has been working on a patent pending bottom-up atomically precise fabrication technique for diamond that circumvents these limitations through designer surface chemistry, hydrogen depassivation lithography and NV center self-assembly during diamond overgrowth. All three organizations have experience with diamond-based materials and by working together they hope to perfect this fabrication technique to enable volume manufacturing of this material at the needed high precision. Additional information about this partnership and their work in diamond quantum material research is available in a press release located on the Quantum Brillance website here.
