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…
Protection of noise squeezing in a quantum interferometer with optimal resource allocation
Wenfeng Huang, Xinyun Liang, Baiqiang Zhu +4
Interferometers are crucial for precision measurements, including gravitational waves, laser ranging, radar, and imaging. The phase sensitivity, the core parameter, can be quantum-…
Sensing performance enhancement via asymmetric gain optimization in the atom-light hybrid interferometer
Zhifei Yu, Bo Fang, Shuying Chen +4
The SU (1,1)-type atom-light hybrid interferometer (SALHI) is a kind of interferometer that is sensitive to both the optical phase and atomic phase. However, the loss has been an u…
Quantum non-demolition measurement based on an SU(1,1)-SU(2)-concatenated atom-light hybrid interferometer
Gao-Feng Jiao, Keye Zhang, L. Q. Chen +2
Quantum non-demolition (QND) measurement is an important tool in the field of quantum information processing and quantum optics. The atom-light hybrid interferometer is of great in…
Nonlinear phase estimation enhanced by an actively correlated Mach-Zehnder interferometer
Gao-Feng Jiao, Keye Zhang, L. Q. Chen +2
A nonlinear phase shift is introduced to a Mach-Zehnder interferometer (MZI), and we present a scheme for enhancing the phase sensitivity. In our scheme, one input port of a standa…
Angular displacements estimation enhanced by squeezing and parametric amplification
Gao-Feng Jiao, Qiang Wang, L. Q. Chen +2
We theoretically study the angular displacements estimation based on a modified Mach-Zehnder interferometer (MZI), in which two optical parametric amplifiers (PAs) are introduced i…
