Since its discovery, quantum entanglement has challenged some of the best established
views of the world: locality and reality. Quantum technologies promise to revolutionize …

Structured light refers to the arbitrarily tailoring of optical fields in all their degrees of freedom
(DoFs), from spatial to temporal. Although orbital angular momentum (OAM) is perhaps the …

Spatial mode (de) multiplexing of orbital angular momentum (OAM) beams is a promising
solution to address future bandwidth issues, but the rapidly increasing divergence with the …

Exploiting a particular wave property for a particular application necessitates components
capable of discriminating in the basis of that property. While spectral or polarisation …

Orbital angular momentum (OAM) has demonstrated great success in the optical
communication field, which theoretically allows an infinite increase of the transmitted …

The goal of machine learning is to facilitate a computer to execute a specific task without
explicit instruction by an external party. Quantum foundations seek to explain the conceptual …

Full control of multiple degrees of freedom of multiple particles represents a fundamental
ability for quantum information processing. We experimentally demonstrate an 18-qubit …

Unitary transformations are the fundamental building blocks of gates and operations in
quantum information processing, allowing the complete manipulation of quantum systems in …

With the emergence of the field of quantum communications, the appropriate choice of
photonic degrees of freedom used for encoding information is of paramount importance …

Characterizing the orbital-angular-momentum (OAM) modes is critically important for OAM-
encoded data transfer. However, traditional characterizing approaches rely on either …
