A strategy toward the realization of a quantum spin processor involves the coupling of spin qubits and qudits to photons within superconducting resonators. To enable the realization of such hybrid architecture, here we first explore the design of a chip with multiple lumped-element LC superconducting resonators optimized for their coupling to distinct transitions of a vanadyl porphyrin electronuclear qudit. The controlled integration of the vanadyl qudit onto the superconducting device, both in terms of number and orientation, is then attained using the formation of nanosheets of a 2D framework built on the vanadyl qudit as a node.

- The study focuses on the magnetic properties of the "cartwheel" heptanuclear cluster [FeO(OCBu)(Me-dea)(HO)], utilizing Mössbauer spectroscopy and sub-Kelvin magnetization measurements to provide insights into its spin frustration.
- The Fe Mössbauer spectra at temperatures above 150 K revealed a specific ratio of doublets that corresponded to different iron sites within the cluster, confirming a previously proposed spin ground state structure where spins are aligned differently among the central and peripheral sites.
- At sub-Kelvin temperatures, the behavior of the cluster changed, showing spin blocking and single-molecule magnet characteristics, along with a defined anisotropy barrier that allows for quantum tunneling at low temperatures.
The controlled integration of magnetic molecules into superconducting circuits is key to developing hybrid quantum devices. Herein, we study [Dy2] molecular dimers deposited into micro-SQUID susceptometers. The results of magnetic, heat capacity and magnetic resonance experiments, backed by theoretical calculations, show that each [Dy2] dimer fulfills the main requisites to encode a two-spin quantum processor.

Introduction/objectives: Enthesitis is a cardinal feature of spondylarthritis (SpA), and the pelvis is a common site of enthesitis. This study aimed to establish the association between pelvic enthesis involvement on pelvic X-ray and SpA diagnosis through a radiographic enthesis index (REI) and to assess the reliability and accuracy of this REI.
Materials And Methods: The participants were SpA patients and a control group composed of patients with chronic lumbar pain without SpA.
