Diamond spin qubits are attracting attention for a combination of high efficiency optical readout and long coherence time, even at room temperature. This project aims to combine efforts in material science and coherence control to advance diamond-based applications in quantum sensing and quantum communication. The joint Diamond Quantum Technology Research Center will tailor diamond materials to realise quantum sensing for biomedical applications. We will also demonstrate elements of quantum networks based on optically active electron spins. The German research teams will contribute their expertise in coherent control of diamond spins, qubits, photonic integration and surface chemistry, while the Japanese research teams will bring their unique expertise in diamond synthesis and their experience in biomedical sensing applications and elements of quantum networks. Both teams will establish a structured PhD programme to enable young researchers to acquire expertise in diamond quantum technologies.
