WP1 is dedicated to the development of material and technologies for the quantum sensor applications in other WPs dealing with the development of the applications (WP2 & WP3). CVD growth processes and preparation for NV doped and ultra-pure diamond with different crystal orientation were developed. Processes are already achieved and are further developed for individual applications. Thorough studies of the effect of surface termination and preparation on the created NV centers was started and is ongoing. NV-doped diamonds with different crystal orientations and doping concentrations were grown and their performances evaluated. This will continue for the remainder of the project.
The goal of WP2 is to develop and realise high-tech components, specific to diamond NV centre sensors, enabling their integration and assembling to concrete devices in WP3. Various components such as laser diode driver, voltage controlled oscillator, trans-impedance oscillator, stable microwave generator and controller have been designed, simulated and fabricated and are ready for the laboratory test before integration into a compact platform. A 4-magnet configuration was used to control independently the set-point and frequency bandwidth of the NV spectrum analyser. Various type of modulations and lock-in amplification with amplitude modulation were tested successfully. Microwave antennas allowing an efficient coupling of the radiofrequency field and the NV centers over large bandwidths have been designed and tested. Graphene electrodes were implanted directly on the surface of diamond crystals with a focused ion beam to allow direct measurement of photoelectric currents without the need of an amplifier.
WP3 is dedicated to the integration of the components and sensors developed in WP2 into functional systems. We have developed a compact spectrum analyser tested outside of the laboratory to measure GSM signals. A widefield-Imager for defect analysis of electronic circuits has been developed. It allows detecting low currents in electronic structures. The development of sensor systems for magnetic field gradiometers monitoring biomagnetic signals is ongoing. The sensor concept has been drafted and validated by system modelling and component testing. A compact ruggedized magnetometer for space applications is under development. The components are developed. The next step will be testing and integration.
WP4 is dedicated to the dissemination of the project results with the goal of raising awareness on quantum sensors among potential customers. We have presented AMADEUS in workshops and conferences as well as to the Quantum Flagship and the Quantum Industry Consortium. Six articles in journals have been published describing the achievements of the project beyond the state of the art. A strong collaboration with several quantum sensor companies outside AMADEUS was established. The website of the project is running and regularly updated (

The objective of WP5 is to determine a clear path to reach target markets for this new technology. Market studies are ongoing in three main fields of applications: telecom, microelectronics and medical domain. The outcomes are expected at the end of the second year of the project. We also facilitate the emergence of EU suppliers of diamond material by testing the crystals they produce. We have also created an Industrial Advisory Board (IAB) with three external renowned experts. The IAB provides input to the project regarding market expectations (performance, cost), trends (competitors) and regulatory considerations. It also assesses the project results and Value Propositions in view of potential marketable products.
WP6 sets-up an effective coordination and management framework for the AMADEUS consortium to ensure progress of the project towards its planned objectives and respect of contractual commitments, as well as to ensure the strategic and operational management of the project. This is a continuous activity throughout the entire project duration. The progress of the project is followed in the monthly meetings of the Executive Board and in in-person General Assembly meetings every 6 months.
