The effect of Quantum Statistics on the sensitivity in an SU(1,1) interferometer
Jie Zeng, Yingxing Ding, Mengyao Zhou +5
We theoretically study the effect of quantum statistics of the light field on the quantum enhancement of parameter estimation based on cat state input the SU(1,1) interferometer. T…
Optimal phase measurements in a lossy Mach-Zehnder interferometer
Wenfeng Huang, Xinyun Liang, Chun-Hua Yuan +2
In this work, we discuss two phase-measurement methods for the Mach-Zehnder interferometer (MZI) in the presence of internal losses and give the corresponding optimum conditions. W…
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…
