AMADEUS is an industry-oriented consortium that will prepare the market uptake of quantum sensors exploiting NV centres in ultrapure diamond, one of the most promising and market-ready technology of quantum sensing. AMADEUS capitalises on the ongoing ASTERIQS project that develops this technology to TRL 4-5 in the ramp-up phase of the Quantum Flagship. Four advanced applications will be pursued up to TRL 6-7 to answer societal and economical needs where no solution exists yet: • Provide a real-time cartography of the RF signal frequencies in 5G communication cellular networks, and further on future 6G, enabling self-optimizing networks in dense area, thus increasing the number of communications and lowering the energy consumption. • Provide a tool to the semiconductor industry to analyse the defects in microelectronics circuits at room temperature and in standard environment in order to increase the throughput and lower the cost production. • Enable monitoring the muscle and brain activity as novel medical diagnostic tool or as brain-machine interface in the future. • Use monitoring of the magnetic field as a multipurpose tool in harsh environment for space applications or for monitoring of the transient currents in electric car batteries. The consortium involves large companies, RTO’s, SME’s and academic partners. It addresses the whole value chain, from the diamond material to the system working in operational environment, along which the workplan is organised. The partners will produce the material and the components that will be assembled in operational systems and will disseminate the results towards large audiences including end-users. Key actions will be taken to support the transfer to market. In collaboration with major European metrology institutes, AMADEUS will contribute to the standardisation and certification of quantum technology. Consequently, AMADEUS will reinforce the European quantum industry for the benefit of Europe’s economy and citizens.

Quantum technologies aim to exploit quantum coherence and entanglement, the two essential elements of quantum physics. Successful implementation of quantum technologies faces the challenge to preserve the relevant nonclassical features at the level of device operation. It is thus deeply linked to the ability to control open quantum systems. The currently closest to market quantum technologies are quantum communication and quantum sensing. The latter holds the promise of reaching unprecedented sensitivity, with the potential to revolutionize medical imaging or structure determination in biology or the controlled construction of novel quantum materials. Quantum control manipulates dynamical processes at the atomic or molecular scale by means of specially tailored external electromagnetic fields. The purpose of QuSCo is to demonstrate the enabling capability of quantum control for quantum sensing and quantum measurement, advancing this field by systematic use of quantum control methods. QuSCo will establish quantum control as a vital part for progress in quantum technologies. QuSCo will expose its students, at the same time, to fundamental questions of quantum mechanics and practical issues of specific applications. Albeit challenging, this reflects our view of the best possible training that the field of quantum technologies can offer. Training in scientific skills is based on the demonstrated tradition of excellence in research of the consortium. It will be complemented by training in communication and commercialization. The latter builds on strong industry participation whereas the former existing expertise on visualization and gamification and combines it with more traditional means of outreach to realize target audience specific public engagement strategies.
