Accelerating quantum optics experiments with statistical learning
Cristian L. Cortes, Sushovit Adhikari, Xuedan Ma +1
Quantum optics experiments, involving the measurement of low-probability photon events, are known to be extremely time-consuming. We present a new methodology for accelerating such…
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…
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…
