Single-shot Precise Ranging using Twisted Light
Long-Zhu Cen, Zi-Jing Zhang, Jun-Yan Hu +7
Over the past decade, optical orbital angular momentum (OAM) modes were shown to offer advantages in optical information acquisition. Here, we introduce a new scheme for optical ra…
Conclusive nonlinear phase sensitivity limit for a Mach-Zehnder interferometer with single-mode non-vacuum inputs
Jian-Dong Zhang, Zi-Jing Zhang, Jun-Yan Hu +4
Many works have stated that nonlinear interactions can improve phase sensitivity beyond the Heisenberg limit scaling of with being the mean photon number. This raises som…
A nearly optimal and robust protocol for nonlinear phase estimation using coherent states
Jian-Dong Zhang, Zi-Jing Zhang, Jun-Yan Hu +4
We propose a protocol for the second-order nonlinear phase estimation with a coherent state as input and balanced homodyne detection as measurement strategy. The sensitivity is sub…
Angular-spectrum-based analysis on the self-healing effect of Laguerre-Gaussian beams after an obstacle
Jian-Dong Zhang, Zi-Jing Zhang, Jun-Yan Hu +4
Self-healing, as an exotic effect, has showed many potential applications. In this paper, we focus on the self-healing effect of Laguerre-Gaussian beams after an obstacle. By takin…
