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…

Orbital-angular-momentum-enhanced estimation of sub-Heisenberg-limited angular displacement with two-mode squeezed vacuum and parity detection
Jiandong Zhang, Zijing Zhang, Longzhu Cen +1
We report on an orbital-angular-momentum-enhanced scheme for angular displacement estimation based on two-mode squeezed vacuum and parity detection. The sub-Heisenberg-limited sens…
