Quantum Computing with Molecules — •Mario Ruben — KIT, IQMT, 76344 Leopolshafen-Eggenstein — CESQ, Université Strasbourg, France

Nuclear spin states in molecules act as quantum registers for quantum operations. We report on the implementation of metal complexes into nanometer-sized spintronic devices by a combination of bottom-up self-assembly and top-down lithography techniques. The controlled generation of magnetic molecular nanostructures will be shown and persistence of their magnetic properties under confinement Molecular Quantum Devices will be proven. The Hilbert space spanned by the nuclear spins will be engineered synthetically and addressed both electrically and optically, partially at the single molecule level. Finally, Grovers quantum search algorithm will be implemented on the nuclear spin register of a TbPc2 Qudit.
