Optimal-classical and quantum-enhanced sensing of a small transverse beam displacement
Wenhua He, Saikat Guha · Conference on Lasers and Electro-Optics · 2022
We evaluate the optimal spatial mode to excite a laser, for estimating a small transverse beam displacement. We also present a quantum-enhanced multi-spatial-mode transmitter, and a path to deriving the optimal multi-mode-entangled squeezed light probe.
