Quantum tomography is an essential experimental tool for testing any quantum technology implementation. Transverse spatial quantum states of light play a key role in many experiments in the field of quantum information as well as in free-space optical communications. In this paper we propose and experimentally demonstrate the tomography of spatial quantum states with a deformable mirror. It may be used to significantly outperform the conventional method with a spatial light modulator (SLM) in terms of speed and efficiency, at the same time providing polarization insensitive operation.

具有可变形反射镜的空间量子状态层析成像

量子断层扫描是测试任何量子技术实现的必不可少的实验工具。光的横向空间量子态在量子信息领域以及自由空间光通信中的许多实验中都起着关键作用。在本文中，我们提出并通过实验证明了具有可变形反射镜的空间量子态的层析成像。就速度和效率而言，它可用于显着优于使用空间光调制器（SLM）的传统方法，同时提供对偏振不敏感的操作。
