Quantum metrology with higher-order exceptional points in atom-cavity magnonics

open access: yesPhysical Review Research
Exceptional points (EPs), which arose early from non-Hermitian physics, significantly amplify the system's response to minor perturbations, and they act as a useful concept to enhance measurement in metrology.
