Abstract: This thesis explores experimental and theoretical approaches to dark matter detection, from gas-based detectors to quantum sensors, tackling the challenge of identifying dark matter, which makes up 27% of the Universe's energy. It reviews astrophysical and cosmological evidence, highlights the Standard Model's limitations, and motivates searches for WIMPs, axions, and dark photons through direct, indirect, and collider-based strategies. The experimental work includes the Micromegas-based TREX-DM experiment for low-mass WIMPs, with studies of argon and neon-based gas mixtures, detector design, shielding, readout, and background suppression. GEM integration boosted gain by up to 45. A UV LED-based internal calibration system was developed for compact, low-background operation, while pressure-dependent gain studies optimized future low-background TPCs. The thesis also advances axion and dark photon searches via haloscopes and introduces the DarkQuantum prototype, a superconducting qubit coupled to microwave cavities for single-photon detection. This system enabled the most stringent exclusion limit on massive dark photon interactions at 5.051 GHz, demonstrating the feasibility of quantum-enhanced detectors. Overall, the work bridges classical and quantum detection techniques, advancing WIMP searches and pioneering compact quantum sensors for axion and dark photon detection, laying the foundation for future high-sensitivity dark matter experiments.

All-Optical Nuclear Quantum Sensing using Nitrogen-Vacancy Centers in Diamond [52.77024349608834]
Microwave or radio-frequency driving poses a significant limitation for miniaturization, energy-efficiency and non-invasiveness of quantum sensors. We overcome this limitation by demonstrating a purely optical approach to coherent quantum sensing. Our results pave the way for highly compact quantum sensors to be employed for magnetometry or gyroscopy applications.

Quantum metamaterial for nondestructive microwave photon counting [52.77024349608834]
We introduce a single-photon detector design operating in the microwave domain based on a weakly nonlinear metamaterial. We show that the single-photon detection fidelity increases with the length of the metamaterial to approach one at experimentally realistic lengths. In stark contrast to conventional photon detectors operating in the optical domain, the photon is not destroyed by the detection and the photon wavepacket is minimally disturbed.
