Effects of losses on the sensitivity of an actively correlated Mach-Zehnder interferometer
Qiang Wang, Gao-Feng Jiao, Zhifei Yu +3
We theoretically studied the quantum Cramér-Rao bound of an actively correlated Mach-Zehnder interferometer (ACMZI), where the quantum Fisher information obtained by the phase-aver…

Atom-light hybrid quantum gyroscope
Yuan Wu, Jinxian Guo, Xiaotian Feng +3
A new type of atom-light hybrid quantum gyroscope (ALHQG) is proposed due to its high rotation sensitivity. It consists of an optical Sagnac loop to couple rotation rate and an ato…
