TL;DR: In this paper, the key fields within structured light from the perspective of experts in those areas, providing insight into the current state and the challenges their respective fields face, as well as the exciting prospects for the future that are yet to be realized.
Journal ArticleDOI
Twisted photons: new quantum perspectives in high dimensions
TL;DR: In this paper, a review of the theoretical differences between qubits and higher dimensional systems, qudits, in different quantum information scenarios is given. And the authors consider the advantages of such higher-dimensional systems, which include higher information capacity and greater protection from eavesdropping.

TL;DR: In this article, the authors used an artificial neural network (ANN) to identify the characteristic mode patterns displayed on a screen at the receiver, and were able to distinguish between 16 different OAM superposition with only a 1.7% error rate.
