Free-space QKD allows for this information to be sent over great distances and in places where fibre-based communications cannot be implemented, such as ground-satellite. The primary limiting factor for free-space links is the effect of atmospheric turbulence, which can result in significant error rates and increased losses in QKD channels. Here, we employ the use of a high-speed Adaptive Optics (AO) system to make real-time corrections to the wavefront distortions on spatial mod","authors_text":"Alessio D'Errico, Ebrahim Karimi, Felix Hufnagel, Khabat Heshami, Lukas Scarfe, Manuel F.
