XMCD study of polynuclear lanthanide-based molecules with non-equivalent sites for Quantum Computing

A major challenge for realizing quantum computation is finding suitable systems to embody quantum bits (qubits) and quantum gates (qugates) in a robust and scalable architecture. An emerging bottom-up approach is to use the electronic spins of polynuclear molecules including weakly interacting, non-equivalent lanthanide (Ln(III)) ions. We developed a synthetic approach to prepare different [LnLn’] and [LnLn’Ln] molecules, permitting the performance of multi-qubit quantum logical operations realized through their derived magnetic states, or implementing quantum-error correction protocols. We propose to use XAS and XMCD technique to study the different local environment and magnetic properties of each Ln within different selected polynuclear lanthanide complexes with non-equivalent sites, to check their suitability for Quantum Computing.
