Abstract
The field of quantum sensing takes advantage of the unique properties of quantum systems and quantum measurement protocols to realize sensing concepts beyond the limits of classical physics. While solid-state sensors are ubiquitous in our daily life, they usually are based on classical sensing concepts. Quantum 1.0 and 2.0 technologies offer intriguing opportunities for improving their sensitivity, noise performance, accuracy, and precision. In this regard, hybrid quantum systems are particularly attractive, since they unite existing solid-state constituents with quantum capabilities. This makes them an ideal test-bed for engineering the transduction of quantum quantities and compare them to established “useful” classical signals. For the tailored transduction between two sub-systems a controlled hybridization of the states participating is desired. In this presentation, I will focus on the solid-state implementation of spin-photon and spin-phonon hybrids which couple spin excitations with gigahertz excitations in superconducting circuits or acoustic resonators. I will discuss both realisations in terms of the emerging dynamics and their sensing capabilities.
