In the quest for ultra-secure, long-range quantum communication, two major challenges stand in the way: the unpredictable nature of atmospheric turbulence and the limitations of current optical ...

The 5.4 km free-space quantum communication link between the University of Ottawa and the National Research Council Canada, where real-time atmospheric turbulence measurements were conducted to train ...

Scientists have produced the finest images of the Sun's corona to date. To make these high-resolution images and movies, the team developed a new 'coronal adaptive optics' system that removes blur ...

Advances in adaptive optics optical coherence tomography (AOOCT) have facilitated the three-dimensional assessment of structural and functional properties of individual retinal cells in the living ...

Prominences, loops and rain are picturesque plasma phenomena occurring in the Sun’s corona. Understanding the structuring and the evolution of coronal plasma on small scales has been intricately ...
