The optical fibre is an essential tool for our communication infrastructure since it is the main
transmission channel for optical communications. The latest major advance in optical fibre …

Abstract 20 years ago, volume nanogratings in silica glass were discovered upon ultrafast
laser irradiation. Since then, these extraordinary self-organised and birefringent structures …

Multimode devices and components have attracted considerable attention in the last years,
and different research topics and themes have emerged very recently. The multimodality can …

High-dimensional entanglement promises to greatly enhance the performance of quantum
communication and enable quantum advantages unreachable by qubit entanglement. One …

Photons are natural carriers of high-dimensional quantum information, and, in principle, can
benefit from higher quantum information capacity and noise resilience. However, schemes …

Photonic waveguides are promising candidates for implementing parallel, ultra-fast and ultra-
low latency interconnects. Such interconnects are an important technological asset for …

In the past decade, the toolkit of quantum information has been expanded to include
processes in which the basic operations do not have definite causal relations. Originally …

Models for quantum computation with circuit connections subject to the quantum
superposition principle have recently been proposed. In them, a control quantum system can …

The recent development of perovskite light emitting diodes (PeLEDs) has the potential to
revolutionize the fields of optical communication and lighting devices, due to their simplicity …

The most common form of measurement in quantum mechanics projects a wavefunction
onto orthogonal states that correspond to definite outcomes. However, generalized quantum …
