| Summary: | A very exciting prospect in coordination chemistry is to manipulate spins within magnetic complexes for the realization of quantum logic operations. An introduction to the requirements for a paramagnetic molecule to act as a 2-qubit quantum gate is provided in this
tutorial review
. We propose synthetic methods aimed at accessing such type of functional molecules, based on ligand design and inorganic synthesis. Two strategies are presented: (i) the first consists in targeting molecules containing a pair of well-defined and weakly coupled paramagnetic metal aggregates, each acting as a carrier of one potential qubit, (ii) the second is the design of dinuclear complexes of anisotropic metal ions, exhibiting dissimilar environments and feeble magnetic coupling. The first systems obtained from this synthetic program are presented here and their properties are discussed.
An introduction to the requirements for a paramagnetic molecule to act as a 2-qubit quantum gate is provided here. |

| Bibliography: | Olivier Roubeau graduated in Inorganic Chemistry at Versailles-Saint-Quentin-en-Yvelines and Paris VI Universities (1998), working with Prof. G. Frey at Institut Lavoisier Versailles, and then obtained his PhD from Leiden University (2002) with Prof. J. Reedijk. He was then assistant professor in Physical Chemistry at University of Bordeaux and CNRS-CRPP until 2008, when he became permanent researcher of the Spanish CSIC at ICMA in Zaragoza, where he focuses on synthesis and physical studies of functional magnetic coordination complexes, and their organization onto surfaces or into soft matter phases. Patrick Gamez (1967, Casablanca, Morocco) studied Chemistry at the University of Lyon in France where he obtained his first degree. In 1995, he received his D. Phil. in the field of enantioselective catalysis and was awarded the French Chemical Society Prize for his PhD research. After a period of postdoctoral research at the Max-Planck-Institut fur Kohlenforschung and at the University of Strasbourg, he joined Leiden University in 1999. Since 2010, he has been ICREA Research Professor at the Universitat de Barcelona. He is (co-)author of about 185 publications. David Aguil received his Masters degree from the Universitat de Barcelona in 2009 under the supervision of Dr Guillem Arom, based on the synthesis and study of coordination complexes with bis--diketone ligands. Currently he is working towards a PhD in the design of magnetic molecules for their application in quantum computing in the Arom Group. This research has been complemented with two stays in Alan Bond's Electrochemistry Group in Monash University, Melbourne (2009), and recently in the Long Group in University of California Berkeley, California (2011). Guillem Arom graduated in Chemistry from the Universitat de Barcelona. He received his PhD in 1999 from Indiana University, with Prof. George Christou, and worked as a Marie-Curie Postdoctoral fellow with Prof. Jan Reedijk (Leiden University) and later with Prof. Richard Winpenny (Manchester University). In 2003, he was awarded a Fellowship Ramn y Cajal at the Universitat de Barcelona, where he is Assistant Professor since 2007. He received the 2008 ICREA Academia prize for excellence in research and is recipient of an ERC Starting Grant since 2011. His research interests are the design and synthesis coordination complexes with functional properties. Fernando Luis received his PhD from the University of Zaragoza (Spain) in 1997, with a thesis on the phenomenon of magnetic quantum tunneling. Between 1998 and 2000, he worked as a Marie Curie post-doctoral researcher at the Kamerlingh Onnes Laboratory (The Netherlands). Since 2003, he has held an appointment with the Spanish Council of Research (CSIC) at the Institute of Materials Science of Aragn. His research focuses on the study of quantum relaxation and quantum phase transitions in magnetic molecular clusters, as well as on the possible applications of these materials to quantum computation.
