Strong converse for the classical capacity of optical quantum communication channels [PDF]
, 2015 We establish the classical capacity of optical quantum channels as a sharp transition between two regimes---one which is an error-free regime for communication rates below the capacity, and the other in which the probability of correctly decoding a ...

The Orbital Angular Momentum Encoding System With Radial Indices of Laguerre–Gaussian Beam
IEEE Photonics Journal, 2018 Orbital angular momentum (OAM) in optical vortices (OV) beams offers a new dimension of space mode because coaxially propagating OV beams with different azimuthal OAM states are mutually orthogonal.
