Ultimate precision limit of SU(2) and SU(1,1) interferometers in noisy metrology
Jie Zeng, Dong Li, L. Q. Chen +2
The quantum Fisher information (QFI) in SU(2) and SU(1,1) interferometers was considered, and the QFI-only calculation was overestimated. In general, the phase estimation as a two-…

Enhanced phase sensitivity in a Mach-Zehnder interferometer via photon recycling
Dong Li, Chun-Hua Yuan, Xiaoping Ma +4
We propose an alternative scheme for phase estimation in a Mach-Zehnder interferometer (MZI) with photon recycling. It is demonstrated that with the same coherent-state input and h…
