€20m project to build room temperature diamond quantum processor
Researchers in Germany are working on a project to develop new techniques for the fabrication and control of a diamond-based quantum processor that operates at room temperature.
German-Australian startup Quantum Brilliance is working with the Fraunhofer Institute for Applied Solid State Physics IAF and the University of Ulm in the €19.9 million ($22.5m) Deutsche Brilliance (DE-Brill) project on next generation diamond quantum processors.
目的是开发用于制造量子微处理器的原子精确技术，并找到用于选择性初始化，读取和操纵量子计算机中具有多个处理器节点的量子的新方法。研究团队认为，解决这些挑战将成为到2025年量子计算机大规模商业化的大规模商业化的重要里程碑。
As part of the collaboration, Fraunhofer IAF and Quantum Brilliance are jointly developing precision manufacturing techniques for the fabrication of scalable arrays of diamond qubits. In addition, Fraunhofer IAF will work on growth processes for diamond substrates of the highest purity and quality. A team at the Institute of Quantum Optics at the University of Ulm is developing scalable readout and control techniques for diamond-based qubits, allowing them to be precisely controlled.
The research project will play an important role in securing Germany as a key business centre for quantum computing as well as give Quantum Brilliance a strong, sustainable position in the industry’s emerging global market, says Dr Mark Mattingley-Scott, European head of Quantum Brilliance.
Mattingley-Scott说：“凭借其研究基础设施和工程知识库，德国为开发和生产量子技术提供了独特的框架。”“此外，德国政府还了解该领域的重要性，并始终促进重要的基础研究。这就是为什么我们最近在斯图加特（Stuttgart）开设了欧洲总部，并着重于与这里的研究机构的合作，将来将在未来的高性能量子微处理器上商业化。”
Quantum Brilliance is among the pioneers in using synthetically created diamonds in quantum computing. Targeted NV centres in diamond where a nitrogen atom takes the place of a carbon atom in the crystal lattice are used in this process to generate qubits, the elementary computational units of a quantum computer.
Quantum accelerators based on synthetic diamonds can be produced in small form factors and operate at room temperature, enabling their use in a variety of real-world environments. A 19-inch server rack module of its diamond-based quantum accelerator is currently available from Quantum Brilliance. Continuing miniaturization with a corresponding increase in the number of qubits is planned over the next several years.
