The profile of our research corresponds to precision metrology and the implementation of quantum processors. In this field, the Division focuses on quantum engineering implemented on isolated structures, such as ions trapped in a Paul trap or nitrogen-vacancy (NV⁻) centres in diamond. An important area of our work is the construction of advanced experimental setups designed to manipulate the quantum states of these structures using laser or microwave radiation. In addition, as part of applications in quantum communication, the Division carries out work related to the generation of optical vortices. From the perspective of atomic physics, we study free atoms and ions using high-resolution laser spectroscopy methods. Our research in this area focuses on the characterisation of electronic levels necessary for a correct description of interactions in atoms. We determine, among other things, the hyperfine structure of electronic levels, isotope shifts, Landé factors, and level energy values. Our research also includes theoretical considerations. We use semi-empirical methods to describe the electronic structure of complex atoms (e.g. rare earths or transition metals). This analysis includes determining the fine and hyperfine structure of complex atoms and the parameterisation of radiative electronic transitions — both those allowed under the so-called selection rules and those forbidden. A major area of our work is the use of semi-empirical and experimental methods to search for and characterise new quantum materials. This makes it possible to explore the application of atomic systems in quantum engineering and metrology in contexts such as Doppler laser cooling methods or the search for stable frequency references for atomic clocks.
