The advancement of superconducting quantum technologies opens new frontiers in precision measurements, enabling the detection of extremely weak signals beyond classical limits. The Microwave Squeezing with Superconducting (meta)materials (MiSS) project focuses on the development of a superconducting quantum sensing platform designed to enhance fundamental physics measurements by using innovative material. A key aspect of this research will be the implementation of quantum squeezing techniques to reduce quantum noise and improve the sensitivity of detection schemes.
One of the primary applications of this platform will be the search for light dark matter candidates, where ultra-sensitive readout systems are required to detect weak interactions that would otherwise be obscured by noise. To achieve this, the project will leverage Traveling Wave Parametric Amplifiers (TWPAs) based on superconducting materials, which provide near-quantum-limited amplification over broad frequency ranges, significantly improving signal-to-noise ratios. Additionally, the platform will incorporate RFSoC (Radio Frequency System-on-Chip) boards, enabling flexible and high-speed digital signal processing for real-time acquisition and analysis of quantum signals. By integrating superconducting circuits, quantum squeezing protocols, TWPA amplifiers, and advanced digital electronics, this research aims to push the boundaries of quantum-enhanced sensing and contribute to the exploration of fundamental physics beyond the current state of the art.
