As an alternative to large magnetically-dilute crystals or concentrated nano-scale deposits of paramagnetic molecules that have been studied so far, the use of pre-formed sub-micronic spherical particles of a doped Gd@Y hydroxycarbonate is evaluated here. Particles with an adjustable number of spin carriers are prepared through the control of both particle size and doping. Bulk magnetic properties and continuous wave and time-domain-EPR spectroscopy show that the Gd spins in these particles are potential qubits with robust quantum coherence. Monolayers of densely-packed particles are then formed interfacially and transferred successfully to the surface of Nb superconducting resonators. Alternatively, these particles are disposed at controlled localizations as isolated groups of a few particles through Dip-Pen Nanolithography using colloidal organic dispersions as ink. Altogether, this study offers new material and methodologies relevant to the development of viable hybrid quantum processors. info:eu-repo/grantAgreement/ES/DGA/E31-20R info:eu-repo/grantAgreement/ES/DGA/E31-23R info:eu-repo/grantAgreement/EC/H2020/862893/EU/Molecular spin qudits offering new hope for quantum computing/FATMOLS This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 862893-FATMOLS info:eu-repo/grantAgreement/ES/MICINN/PID2019-105881RB-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2020-1183294RB-I00 info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 12.2 2023 CHEMISTRY, MULTIDISCIPLINARY 26 / 231 = 0.113 2023 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 39 / 439 = 0.089 2023 Q1 T1 3.376 2023 Electrical and Electronic Engineering 2023 Q1 Process Chemistry and Technology 2023 Q1 Mechanics of Materials 2023 Q1 Materials Science (miscellaneous) 2023 Q1 18.9 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Urtizberea, Ainhoa Universidad de Zaragoza (orcid)0000-0002-8424-9780 Natividad, Eva Universidad de Zaragoza (orcid)0000-0003-2553-0633 Martínez, Jesús I.
