Incorporating non-Hermitian dynamics into quantum systems leads to a range of intriguing phenomena, including non-reciprocity, parity–time symmetry breaking, and the emergence of exceptional points, at which two or more eigenstates coalesce. These features can result in enhanced sensitivity to weak perturbations, offering a distinct approach to quantum sensing.During the talk, I will discuss the emergence of exceptional points in a hybrid system composed of two distinct gases—rubidium vapor and a noble gas—and demonstrate how this framework enhances sensitivity to magnetic fields. I will also show how such a system can be employed to search for non-magnetic interactions.
