Nematic liquid-crystal devices are a powerful tool to structure light in different degrees of freedom, both in classical and in quantum regimes. Most of these devices exploit the possibility of introducing a position-dependent phase retardation eithe

The polarization of a monochromatic optical beam lies in a plane and, in general, is described by an ellipse, known as the polarization ellipse. The polarization ellipse in the tight-focusing (nonparaxial) regime forms nontrivial three-dimensional to

Underwater quantum communication has recently been explored using polarization and orbital angular momentum (OAM). Here, we show that spatially structured modes, e.g., a coherent superposition of beams carrying both polarization and OAM, can also be

The characterization of quantum processes, e.g. communication channels, is an essential ingredient for establishing quantum information systems. For quantum key distribution protocols, the amount of overall noise in the channel determines the rate at

Structured photons are particularly useful for quantum information tasks, including quantum communications and simulations. This is attributed to the fact that structured states provide access to a theoretically unbounded Hilbert space for encoding i

Quantum walks serve as novel tools for performing efficient quantum computation and simulation. In a recent experimental demonstration [1] we have realized photonic quantum walks for simulating cyclic quantum systems, such as hexagonal lattices or ar

We examine the propagation of optical beams possessing different polarization states and spatial modes through the Ottawa River in Canada. A Shack-Hartmann wavefront sensor is used to record the distorted beam's wavefront. The turbulence in the under

Emission spectra from collisions of 8 keV He + and H 2 + with neutral naphthalene, benzene, acetylene and methane were acquired over 190–1020 nm on a modified double-focusing mass spectrometer. The bands, emission intensities and the minimum excita
