Description
Dark matter remains one of the central problems in fundamental physics, and cavity-based searches are a leading method for probing ultralight candidates such as axions and dark photons. In this talk, I will present a quantum sensing protocol for coupled qubit–oscillator systems aimed at improving cavity-based dark matter detection. By combining coherent displacement and squeezing, the weak dark matter signal is encoded into an enhanced geometric phase. This increases the quantum Fisher information beyond the standard quantum limit and significantly improves sensitivity to both dark photons and axions. The method suggests a promising quantum-enhanced strategy for future cavity dark matter searches.
