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…
Coherence Protection of Electron Spin in Earth-field Range by All-optical Dynamic Decoupling
Peiyu Yang, Guzhi Bao, L. Q. Chen +1
In recent years, unshielded atomic systems have been attracting researchers' attention, in which decoherence is one of the major problems, especially for high precision measurement…
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…
Efficient Raman Frequency Conversion by Feedbacks of Pump and Stokes Fields
Bing Chen, Kai Zhang, Chun-Hua Yuan +5
We experimentally demonstrate efficient Raman conversion to respective Stokes and anti-Stokes fields in both pulsed and continuous modes with a Rb-87 atomic vapor cell. The convers…
