Diamond QPU architecture

The joint project “DE-Brill” aims to create the technological prerequisites for the realization of scalable diamond-based quantum microprocessors (QPUs), which can be applied, for example, in the field of edge computing. In cooperation with the start-up Quantum Brilliance, which is responsible for the commercial use of the project results, Fraunhofer IAF is applying its expertise in diamond epitaxy as well as wafer processing and characterization to develop growth processes of high-purity, (111)-oriented diamond and precise manufacturing techniques for the fabrication of scalable diamond qubit arrays. In parallel, the Institute of Quantum Optics at Ulm University is working on new methods for the readout and control of diamond qubits.
