Description
The direct detection of sub-GeV dark matter particles is a major experimental challenge. In this low energy range, the energy transfer between sub-GeV particles and a solid target media is only in the range of a few millielectron-volts to a few electron-volts, which dares the current capabilities of sensors. However, the application of state-of-the-art developments in quantum information science show promise for detecting low-energy particles.
In this presentation, we will discuss some work being done in the frame of the CSIC Quantum Technology Platform, which includes research groups belonging to ICMAB, IFCA, INMA, and IMB-CNM. Specifically, we focus on the development of superconducting micro-calorimeters that could detect athermal phonons created by the interaction of dark matter particles with selected single crystals. Complementary, the IMB-CNM is involved on several projects to fabricate qubit solid-state implementations. In collaboration with IFAE and LSC, for instance, the aim is to understand the interaction and effect of cosmic rays with superconducting devices and circuits. We will provide details of our progress on manufacturing the sensing and qubit devices, as well as of the detection concept of sub-Gev DM particles.
