The current understanding of the role of topology in non-Hermitian (NH) systems and its far-
reaching physical consequences observable in a range of dissipative settings are reviewed …

Topological photonics is a rapidly emerging field of research in which geometrical and
topological ideas are exploited to design and control the behavior of light. Drawing …

Non-equilibrium topological phenomena can be induced in quantum many-body systems
using time-periodic fields (for example, by laser or microwave illumination). This Review …

Photonic quantum technologies represent a promising platform for several applications,
ranging from long-distance communications to the simulation of complex phenomena …

Twisted photons can be used as alphabets to encode information beyond one bit per single
photon. This ability offers great potential for quantum information tasks, as well as for the …

Quantum simulators are controllable quantum systems that can be used to mimic other
quantum systems. They have the potential to enable the tackling of problems that are …

Quantum walks, the quantum mechanical counterpart of classical random walks, is an
advanced tool for building quantum algorithms that has been recently shown to constitute a …

Quantum random walk is the quantum counterpart of a classical random walk. The classical
random walk concept has long been used as a computational framework for designing …

Environmental noise and disorder play critical roles in quantum particle and wave transport
in complex media, including solid-state and biological systems. While separately both effects …

Topological phases exhibit some of the most striking phenomena in modern physics. Much
