Coupling organic free-radical molecules to lumped-element superconducting resonators 2024 Access copy available to the general public Unrestricted A promising route toward the realization of a molecular spin quantum processor relies on coupling magnetic molecules to individual photons confined within superconducting resonators. As a simple approximation to such a hybrid scheme, here we explore the conditions that determine the collective coupling of DPPH organic free radicals to lumped-element LC superconducting resonators. In these chips, multiple resonators are coupled to a single readout line. This enables designing the relevant resonator properties, such as resonance frequency, cavity volume, and impedance while keeping a perfect transmission for the device. Here, we exploit these design possibilities to achieve a coherent spin-photon coupling regime. Besides, we study how this coupling depends on the relative orientation of the external dc magnetic field concerning the photon magnetic field and the spins locations concerning the chip surface. info:eu-repo/grantAgreement/ES/AEI/AEI PID2022-140923NB-C21 info:eu-repo/grantAgreement/ES/DGA/E09-23R info:eu-repo/grantAgreement/ES/MICINN/CEX2020-001039-S info:eu-repo/grantAgreement/EUR/MICINN/TED2021-131447B-C21 info:eu-repo/grantAgreement/EUR/MICINN/TED2021-131447B-C22 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.8 2024 PHYSICS, APPLIED 172 / 187 = 0.92 2024 Q4 T3 0.2 2024 Physics and Astronomy (miscellaneous) 2024 Q4 0.9 2024 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion de Ory, M.
