Enhancing the sensitivity of rotation in a multi-atom Sagnac interferometer
Fei Yao, Yanming Che, Yuguo Su +3
We investigate quantum sensing of rotation with a multi-atom Sagnac interferometer and present multi-partite entangled states to enhance the sensitivity of rotation frequency. For…

Multiqubit matter-wave interferometry under decoherence and the Heisenberg scaling recovery
Yanming Che, Jing Liu, Xiao-Ming Lu +1
Most matter-wave interferometry (MWI) schemes for quantum sensing are so far evaluated in ideal situations without noises. In this work, we provide assessments of generic multiqubi…

Phase-space geometric Sagnac interferometer for rotation sensing
Yanming Che, Fei Yao, Hongbin Liang +2
Quantum information processing with geometric features of quantum states may provide promising noise-resilient schemes for quantum metrology. In this work, we theoretically explore…
