As part of the EIC Pathfinder Open 2026 call, the ARTEMIS project — All-Electric Quantum Magnetic Field Sensing with Molecular Spintronics — was selected among 43 projects, with the Jožef Stefan Institute participating as a partner (led by Prof. Dr. Viktor Kabanov).
The long-term vision of ARTEMIS is to develop a fully-fledged all-electrical molecular magnetic field quantum sensor with exceptionally high sensitivity, in the range of fT/√Hz. Highly deployable magnetic field quantum sensors are highly desirable, for example in the health sector, to monitor brain currents or to develop more affordable MRI sensors, in security, for land mine detection, in navigation, for GPS-less navigation devices. Current magnetic field quantum sensors, such as SQUIDs, SERFs and NV magnetometers although very sensitive, are cumbersome and expensive and cannot be deployed as widely as classical GMR and TMR sensors; the latter instead lack the exceptional sensitivity of the former. The key innovation of the project lies in using paramagnetic molecules as molecular spin qubits. Their quantum states will be initialised using a spin-polarised electrical current, while magnetic field sensing will be achieved through microwave pulses and electrical readout via magnetoresistance. As part of the project, the researchers will develop a laboratory-scale sensor prototype, experimentally evaluate its sensitivity and use theoretical modelling to investigate the physical processes underlying its operation. The results will provide a foundation for further technological development and an assessment of the potential practical applications of this new generation of quantum sensors.
The Slovenian partner, JSI, will provide comprehensive theoretical support for the project’s experimental work. Its key task will be to develop theoretical models describing the transfer of magnetic moments from a spin-polarised electrical current to paramagnetic molecules. This research will contribute to a better understanding of the physical processes underlying molecular quantum magnetic field sensors and support the development and optimisation of new sensing technologies.
