Atom-light-correlated quantum interferometer with memory-induced phase comb
Wenfeng Huang, Xinyun Liang, Jie Zhao +7
Precise phase measurements by interferometers are crucial in science for detecting subtle changes, such as gravitational waves. However, phase sensitivity is typically limited by t…

Quantum Metrology with Higher-order Exceptional Points in Atom-cavity Magnonics
Minwei Shi, Guzhi Bao, Jinxian Guo +1
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 enha…
