- The search for dark matter constitutes one of the most pressing challenges in modern physics. Axions, hypothetical pseudoscalar particles, are compelling candidates to address both the strong CP problem and the dark matter enigma. While extensive experimental efforts have focused on QCD axions in the micro-electronvolt ($mu$eV) range, the parameter space for MeV-scale axion-like particles remains largely unexplored. This paper presents initial experimental limits on axion-photon coupling in the micro-electronvolt ($mu$eV) range, derived from a novel detection scheme utilizing a high-Q superconducting quantum resonator. Operating within a dilution refrigerator environment, the resonator is designed with features that enable future exploration of the MeV-scale, detecting the resonant conversion of axions into microwave photons in the presence of a strong magnetic field. By carefully characterizing the system's noise performance and employing advanced signal processing techniques, we establish new constraints on the axion-photon coupling constant for axion masses in the $mu$eV range, demonstrating the system's scalability and potential for MeV-scale investigations. These pioneering results establish a robust experimental framework, demonstrating the potential of superconducting quantum technologies to probe previously inaccessible regions of the MeV-scale axion parameter space. The methodology developed here paves the way for future experiments with enhanced sensitivity, contributing significantly to the broader quest for fundamental particles beyond the Standard Model.
