We characterize it by preparing the [Lu-Ce-Lu] and [Er-La-Er] analogues, which contain only one of the two types of qubit, and by combining magnetometry, low-temperature specific heat and electron paramagnetic resonance measurements on both the elementary constituents and the trimer. Using the resulting parameters, we demonstrate by numerical simulations that the proposed molecular device can efficiently suppress pure dephasing of the spin qubits.2020http://zaguan.unizar.es/record/9609610.1039/d0sc03107khttp://zaguan.unizar.es/record/96096oai:zaguan.unizar.es:96096info:eu-repo/grantAgreement/ES/DGA/E09-17R-Q-MADinfo:eu-repo/grantAgreement/ES/DGA/E31-17Rinfo:eu-repo/grantAgreement/EC/FP7/258060/EU/Design and Preparation of Functional Molecules for Quantum Computing and Information Processing/FUNCMOLQIPinfo:eu-repo/grantAgreement/EC/H2020/862893/EU/Molecular spin qudits offering new hope for quantum computing/FATMOLSThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 862893-FATMOLSinfo:eu-repo/grantAgreement/ES/MICINN/CTQ2015-64486-Rinfo:eu-repo/grantAgreement/ES/MICINN/CTQ2015-68370-Pinfo:eu-repo/grantAgreement/ES/MICINN/MAT2017-86826-Rinfo:eu-repo/grantAgreement/ES/MICINN/PCI2018-093116info:eu-repo/grantAgreement/ES/MICINN/PGC2018-098630-B-I00info:eu-repo/grantAgreement/ES/MICINN/RTI2018-096075-B-C21info:eu-repo/grantAgreement/EUR/MOLSPIN-COST/CA15128info:eu-repo/grantAgreement/EUR/QUANTERA/SUMOChemical Science 11, 38 (2020), 10337-10343by-nchttp://creativecommons.org/licenses/by-nc/3.0/es/info:eu-repo/semantics/openAccess
