Several quantum protocols, with applications ranging from fundamental studies to cryptographic scenarios, can be enhanced through the generation and manipulation of quantum states that belong to high-dimensional Hilbert spaces. For this reason, it is

Abstract Quantum walks represent paradigmatic quantum evolutions, enabling powerful applications in the context of topological physics and quantum computation. They have been implemented in diverse photonic architectures, but the realization of two-p

The authors introduce linear gears to measure mechanical displacements with high sensitivity. Such gears covert tiny transverse shifts between two birefringent devices into a giant polarization rotation of a laser beam.

Quantum walks are processes that model dynamics in coherent systems. Their experimental implementations proved to be key to unveiling novel phenomena in Floquet topological insulators. Here, we realize a photonic quantum walk in the presence of a syn

In two, three and even four spatial dimensions, the transverse responses experienced by a charged particle on a lattice in a uniform magnetic field are fully controlled by topological invariants called Chern numbers, which characterize the energy ban

The detection of topological invariants in the bulk remains challenging even in state-of-the-art experiments. Here, Cardanoet al. propose a method to read-out the Zak phases and topological invariants in one-dimensional chiral systems and detect thos

In a Quantum Walk (QW) the "walker" follows all possible paths at once through the principle of quantum superposition, differentiating itself from classical random walks where one random path is taken at a time. This facilitates the searching of prob

Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols. Here, we demonstrate a functional source of high-dimensional, noi

Topological phases play a fundamental role in a variety of physical systems, yet there is a lack of efficient tools for revealing the occurrence of associated quantum transitions. Here, Cardano et al.report that such transitions can be identified in

The topology of one-dimensional chiral systems is captured by the winding number of the Hamiltonian eigenstates. Here we show that this invariant can be read out by measuring the mean chiral displacement of a single-particle wave function that is con
