论文摘要
我们考虑通过特定的光束塑形技术来区分电子显微镜中的大分子结构的问题。我们的方法基于从每个电子状态提取的哪种分子信息最大化。为此,最佳可观察物是在量子状态歧视的框架内得出的,这使人们可以从探针的量子特征中充分说明。我们模拟了在广义轨道角动量(OAM)分类器上实现这种最佳可观察的,并根据最著名的真实空间方法进行基准测试。
We consider the problem of discriminating macromolecular structures in an electron microscope, through a specific beam shaping technique. Our approach is based on maximizing the which-molecule information extracted from the state of each electron. To this aim, the optimal observables are derived within the framework of quantum state discrimination, which allows one to fully account from the quantum character of the probe. We simulate the implementation of such optimal observable on a generalized orbital angular momentum (OAM) sorter and benchmark its performance against the best known real space approach.
