Comparison of Laguerre-Gauss and Pixel Modes for High-Dimensional Multiplexing and QKD
* Felix Hufnagel, University of Ottawa, Canada Ebrahim Karimi, University of Ottawa Itay Kozlov, University of Ottawa Justin Tam, University of Ottawa Spatial modes of light such as the Laguerre-Gauss modes are popular in free-space communication for spatial mode multiplexing and high-dimensional quantum communication protocols. One can also consider a pixel mode approach to spatial multiplexing, where the beam is subdivided into spatially separated circular modes which serve as orthogonal states for classical or quantum purposes. We investigate the limiting factors in both approaches with respect to the channel loss and mode crosstalk over long distances considering the effect of divergence and atmospheric turbulence. We then investigate the ability of an adaptive optics system to mitigate these challenges in both cases, and experimentally explore the results using a fast adaptive optics system in the lab. |

Sharper Images Through Quantum Imaging
* Robert W. Boyd, University of Ottawa and University of Rochester, Canada Quantum imaging is a research area that seeks to produce “better” images using quantum methods We review some recent research in the field of quantum imaging. |
