We propose a novel experiment, the Canfranc Axion Detection Experiment (CADEx), to probe dark matter axions with masses in range 330-460 $\mu$eV, within W-band (80-110 GHz), an unexplored parameter space well-motivated window of Quantum ChromoDynamics (QCD) axions. The experimental design consists microwave resonant cavity haloscope high static magnetic field coupled highly sensitive detecting system based on Kinetic Inductance Detectors via optimized quasi-optics (horns and mirrors)....
Abstract Lack of reproducibility hampers molecular devices integration into large-scale circuits. Thus, incorporating operando characterization can facilitate the understanding multiple features producing disparities in different devices. In this work, we report realization hybrid graphene field effect transistors (m-GFETs) based on 11-(Ferrocenyl)undecanethiol (FcC 11 SH) micro self-assembled monolayers (μSAMs) and high-quality (Gr) a back-gated configuration. On one hand, Gr enables redox...
Abstract Superconducting resonators are critical components in a wide range of quantum technologies, including high‐performance detectors and amplifiers. However, their performance is often limited by noise sensitivity issues caused two‐level systems (TLS) originated from oxide layers, such as , the device.

Superconducting resonators play a crucial role in developing forthcoming quantum computing schemes. The complete integration of molecular spin-based bits with superconducting still requires further developments, notably maintaining low-loss resonances and high quality factors.
