Detection of of Dipole-Dipole Interactions in Rare-Earth-Ion for Applications in Quantum Computing

Quantum technologies are today at the forefront of scientific research, as they are expected to have a very strong impact in numerous fields. The primary objective in both research groups, the QPSA lab and the NPQO lab is to develop the physical building blocks necessary for quantum communication. Many different quantum systems are currently being investigated to perform computing, but each has its own strengths and drawbacks.Thus, the exploration of new quantum platforms is an ongoing research area. The aim of this project is to investigate the potential of rare-earth ions-doped crystals (REIC), an emerging platform for quantum computing. A promising REIC, praseodymium, was chosen to be investigated for its suitability in creating multi-quibit gates. We aim to detect dipole-dipole interactions between ions in praseodymium-doped nanoparticles coupled to a fiber cavity as a first step towards this goal. QPSA has with a strong expertise in fiber-integrated open-access cavity interfaces and rare-earth doped solids, while NPQO excels at hollow waveguides and phonic crystal-based cavities as well as integration of photonic crystal waveguides with solid-state emitters. The outlined project will allow for the knowledge exchange in experimental techniques and design related to solid-state quantum information platforms and photonic integration.
