This project was granted by the ANR in 2019. The objective of the project is the specific design and the synthesis of organometallic complexes of lanthanides that possess slow magnetic relaxation properties with high blocking temperature. The use of the typical ligands used in organometallic chemistry is proposed herein (Cp), (Cot). The use of the cyclononatetraenyl (Cnt) ligand, a large mono-anionic Huckël-aromatic ligand is also proposed: it will lead to unique geometric features in both divalent and trivalent lanthanide chemistry.

Our project aims to explore the potential of Paramagnetic Complexes (PCs) to play the role of robust solid-state quantum bits (qubits) for quantum information processing (QIP). We exploit the flexibility and versatility of lanthanide-containing complexes to design and prepare molecular crystals made of molecules with targeted electronic and nuclear spin architectures adapted to the demonstration of quantum logic gates, optical quantum storage, and telecommunication. 
Theoretical chemistry together with optical and Electron Paramagnetic Resonance spectroscopies will assess the potential of the molecules for QIP. Ultimately, we want to assess the suitability of molecules as a platform for quantum computing, one- and two-qubit quantum gates. The synthesis part is led by Grégory Nocton with Grégory Danoun and we have several collaborations with Stefan Minassian (LBNL, Berkeley), Thomas Gianetti (U of Arizona); Kasper Pedersen (DTU), and in France with Talal Mallah (University Paris-Saclay).
