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…
Conclusive Precision Bounds for SU(1,1) Interferometers
Chenglong You, Sushovit Adhikari, Xiaoping Ma +3
In this paper, we revisit the quantum Fisher information (QFI) calculation in SU(1,1) interferometer considering different phase configurations. When one of the input modes is a va…
Enhanced signal-to-noise ratio in Hanbury Brown Twiss interferometry by parametric amplification
Xiaoping Ma, Chenglong You, Sushovit Adhikari +2
The Hanbury Brown Twiss (HBT) interferometer was proposed to observe intensity correlations of starlight to measure a star's angular diameter. As the intensity of light that reache…
Sub-shot-noise-limited phase estimation via SU(1,1) interferometer with thermal states
Xiaoping Ma, Chenglong You, Sushovit Adhikari +3
We theoretically study the phase sensitivity of an SU(1,1) interferometer with a thermal state and squeezed vacuum state as inputs and parity detection as measurement. We find that…
