TL;DR: A proof-of-principle experiment that indicates the feasibility of high-dimensional QKD based on the transverse structure of the light field allowing for the transfer of more than 1 bit per photon and demonstrates that, in addition to having an increased information capacity, multilevel QK D systems based on spatial-mode encoding can be more resilient against intercept-resend eavesdropping attacks.

Dynamics of microparticles trapped in a perfect vortex beam
TL;DR: A linear relationship is observed between the rotation speed and orbital angular momentum content of the beam and a perfect vortex beam with integer or fractional topological charges is observed.

Capacity limits of spatially multiplexed free-space communication
TL;DR: In this article, the capacity limits of the orbital angular momentum multiplexing for free-space optical communication were revealed, and it was shown that it is not an optimal technique for realizing the capacity limit of a free space communication channel.

Six-parameter Gaussian modes in free space
TL;DR: In this paper, a derivation of free-space Gaussian modes described by six parameters is given for a beam traveling in the $z$ direction, and it is shown that the beam waist for the properties in the planes of constant $y$ and constant $x$ need not coincide.
