Description
The SQMS Center develops state-of-the-art superconducting and quantum technologies for ultra-sensitive searches for physics beyond the Standard Model. By combining superconducting radio-frequency cavities with quantum devices, SQMS is pursuing a broad experimental program targeting axion and dark photon dark matter, high-frequency gravitational waves, and other weakly interacting particles. This talk will begin with a short overview of the SQMS quantum sensing program, highlighting the enabling technologies and the range of experimental efforts currently underway.
The talk will then focus on representative experiments, that may include SHADE (Superconducting Heterodyne Axion Dark matter Experiment), a search for ultralight axions based on heterodyne frequency conversion in superconducting cavities, and the recent Dark SRF results from the reanalysis of the experimental data using an improved treatment of cavity frequency fluctuations. The latter analysis provides a more robust framework for mitigating frequency instabilities and is expected to benefit future cavity-based dark matter searches across the SQMS program.
