报告摘要：

The synthetic engineering of the nuclear spin degree of freedom in lanthanide molecules will be shown with the goal to make the respective isotopologue complexes accessible as quantum registers in quantum protocols.[1-2] Therefore, we report on the implementation of lanthanide (III) metal complexes into spintronic and optical devices. The Hilbert space spanned by the nuclear spins in different ALn(III) isotopologues will be addressed electrically [3-11] and optically [12-14], partially at the single-molecule level.  The main motivation is to realize long-sought coherent photon-nuclear-spin interfaces for superposition and entanglement of larger qubit ensembles, even non-locally distributed. Thereby, it was demonstrated that ultra-narrow optical linewidths in separately synthesized molecular lanthanide crystals of 151Eu(III) and 153Eu(III) isotopologues enable the optical addressing of nuclear spins levels in mono- and dinuclear complexes. [12-13] The first-time observation of an optically detected Nuclear Magnetic Resonance (OD-NMR) experiment in a 151Eu(III) complex will be reported (Figure 1). [14]

报告人简介：

Mario Ruben obtained his Ph.D. in 1998 from the University of Jena, Germany. During a DAAD post-doctoral fellowship, he worked in the research group of the Nobel Prize Winner Prof. J.-M. Lehn at the ISIS in Strasbourg, France. In 2001, he moved to the Institute of Nanotechnology in Karlsruhe and in 2010, he accepted a position as Professor at the University de Strasbourg, France. In 2013, he became Full Professor for Molecular Materials at the Institutes of Inorganic Chemistry and of Nanotechnology at the KIT. His research interests involve the design, synthesis, and physical characterization of functional molecules and their implementation and integration into operational nanosystems for molecular spintronic and quantum devices. Since 2026, he is holding the ERC Advanced Grant “Hilbert Molecules”. He published more than 360 papers with an H-index of 81 (Google Scholar).
