报告题目：Novel Light Dark Matter Detection with Quantum Parity Detector Using Qubit Arrays

报告人：宋宁强 副研究员（中国科学院理论物理研究所）

报告摘要：We present the design and the sensitivity reach of the Qubit-based Light Dark Matter detection experiment. We propose the novel two-chip design to reduce signal dissipation, with quantum parity measurement to enhance single-phonon detection sensitivity. We demonstrate the performance of the detector with full phonon and quasiparticle simulations. The experiment is projected to detect 10 meV-100 meV energy deposition with nearly 100% efficiency and high energy resolution. The sensitivity to sub-MeV  dark matter scattering cross section is expected to be advanced by orders of magnitude for both light and heavy mediators, and similar improvements will be achieved for axion and dark photon absorption in the sub-eV mass range.
