Meanwhile two-dimensional (2D) networks of spin qubit nodes could provide a means to achieve the control of qubit localization and orientation required for implementation of molecular spin qubits in hybrid solid-state devices. Here, the 2D metal-organic framework [{VO(TCPP)}Zn2(H2O)2]8 is reported and its vanadyl porphyrin node is shown to exhibit superior spin dynamics and to enable coherent spin manipulations, making it a valid spin qubit candidate. Nanodomains of the MOF 2D coordination planes are efficiently formed at the air-water interface, first under Langmuir-Schaefer conditions, allowing mono- and multiple layer deposits to be transferred to a variety of substrates. Similar nanodomains are then successfully formed in situ on the surface of Nb superconducting coplanar resonators. Transmission measurements with a resonator with a 14 µm-wide constriction allow to estimate that the single spin-photon coupling G1 of the vanadyl spins in the nanodomains is close to being optimal, at ca. 0.5 Hz. Altogether, these results provide the basis for developing a viable hybrid quantum computing architecture.2020http://zaguan.unizar.es/record/9708210.1039/c9mh01594ahttp://zaguan.unizar.es/record/97082oai:zaguan.unizar.es:97082info:eu-repo/grantAgreement/ES/DGA/E09-17Rinfo:eu-repo/grantAgreement/ES/DGA/E31-17Rinfo:eu-repo/grantAgreement/ES/MEC/FPU14-05367info:eu-repo/grantAgreement/ES/MICINN/RTI2018-096075-B-C21info:eu-repo/grantAgreement/ES/MINECO/CTQ2015-64486-Rinfo:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2017-86826-Rinfo:eu-repo/grantAgreement/ES/MINECO/MAT2016-78257-Rinfo:eu-repo/grantAgreement/ES/MINECO/PCI2018-093116Materials Horizons 7, 3 (2020), 885-897All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
