    "abstract": "We investigate novel strategies to extend the sensitivity of dark matter direct detection experiments to energy deposits well below the thresholds of conventional detectors. In liquid-argon time-projection chambers equipped with silicon photomultipliers (SiPMs), we show that improved optical readout, combined with a nuclear dielectric constant (NDC) correction to the WIMP nucleus interaction, enhances the response to low-momentum-transfer nuclear recoils. The NDC effectively amplifies the interaction strength at small recoil energies, increasing the expected ionization and scintillation yields without modifying the high-energy behavior constrained by calibration data. When coupled to SiPM based light collection, this mechanism lowers the effective detection threshold to the subKeV regime, significantly improving sensitivity to low-mass WIMPs and other weakly interacting particles. Complementarily, we present the design and projected performance of a qubit-based detector optimized for ultra-low-energy depositions. A novel two-chip architecture is employed to minimize signal dissipation, while quantum parity measurements enable enhanced single-phonon sensitivity. Full simulations of phonon propagation and quasiparticle dynamics demonstrate that energy deposits at the level of $\\gtrsim 30 meV$ can be detected with nearly unit efficiency and high energy resolution. This capability is expected to advance sensitivity to dark-matter scattering for masses $m_\\chi \\gtrsim 0.01 MeV$ by several orders of magnitude for both light and heavy mediators, and to enable competitive searches for axion and dark-photon absorption in the $0.04 - 0.2 eV$ mass range.",
