The “perfect” vortex is a new class of optical vortex beam having ring radius independent of
its topological charge (order). One of the simplest techniques to generate such beams is the …

We present a detailed security analysis of a d-dimensional quantum key distribution protocol
based on two and three mutually unbiased bases (MUBs) both in an asymptotic and finite …

Spatial entanglement is at the heart of quantum enhanced imaging applications and high-
dimensional quantum information protocols. In particular, for imaging and sensing …

The detection and characterization of quantum states of light plays an important role in
quantum science. Traditional methods use single-photon detectors, but these are generally …

Losses should be accounted for in a complete description of quantum imaging systems, and
yet they are often treated as undesirable and largely neglected. In conventional quantum …

Multipartite entanglement is the crucial requirement for quantum information processing,
quantum computation, quantum communication and quantum sensing. Therefore, the …

With the wealth of super-resolution techniques available in the literature it is useful to
provide a succinct review of the general concepts involved in the different schemes. In this …
