SUMMARY:Heterometallic lanthanide coordination complexes for quantum  technologies
DESCRIPTION:\n\n\nSpeaker:  Prof. Guillem AromíAffiliation:  University of Barcelona\, Barcelona\, SpainLink to the MSTeams meetingMeeting ID: 353 297 339 081Passcode: tu3CAwDownload Teams | Join on the web \n\n\n\nMolecular  materials  find  applications  in  many  crucial  areas  of technology.  For  example\,  molecular  electronic  spins  are  potential  qubits  and  qugates  in  quantum  computing [1-2].   Some   of   their   advantages   over   other   technologies   are   their   reproducibility  (crucial  for  a  scalable  quantum  technology)  and  the  versatility  of  chemical design. The latter enables the preparation of molecules to host several spins\, thus embodying various qubits capable to undertake complex tasks. Lanthanides are good spin-qubit candidates in these systems\, as they exhibit good coherent properties and a diversity of electronic features. We have designed a ligand-based strategy to synthesize di- or trinuclear lanthanide complexes exhibiting distinct coordination sites within  one  molecule  type.  This  provides  a  means  of  preparing  pure  heterometallic  complexes that can be of the [LnLn’] or the [LnLn’Ln] type\, where the nature of the Ln and  the  Ln’  metals  can  vary  extensively [3-5]  Preparation  of  selective  heterometallic  complexes  in  one  step  is  extremely  rare  and  the  trinuclear  case  is  unique.  The  performance of these molecules as multi-qubit quantum gates will be discussed.  \n\n\n\n\n\n\n\nAromí\, G.; Aguilà\, D.; Gamez\, P.; Luis\, F.; Roubeau\, O.\, Chem. Soc.
