The usage of QKD protocols through the current terrestrial infrastructure is limited to a hundred kilometers due attenuation problems with fiber. This implies that satellite will be necessary for transmission quantum keys in order avoid these limitations. Therefore, debate does not lie need but rather what type best suited, and specifically GEO vs LEO satellites. analysis trivial should consider only link budgets physical layer as it has been done up date. It also even more important...
The Institute of Astrophysics the Canary Islands, IAC, and specifically its technology transfer division IACTEC, has a long history participation in free-space optical communications projects (FSOC). These activities are nowadays being pushed forward to achieve practical applications quantum key distribution, leveraging facilities experience FSOC field "know-how" Adaptive Optics. A Free-Space Communications Laboratory been installed at IACTEC clean rooms, intended be used as permanent...
This article summarizes the results of a system engineering approach to design Transportable Optical Ground Station (TOGS) intended be used for quantum key distribution in number scenarios. Key requirements are listed and product breakdown is proposed, identifying parts, which specific particular scenario others, common many them, thus will allow their implementation shared. We proposing use Adaptive Optics (AO) compensation effects atmospheric turbulence, order improve efficiency signal...
IACTEC, as the technology transfer division of Instituto de Astrofísica Canarias (IAC), is initiating a program towards practical applications optical communications and specifically quantum key distribution, taking advantage its facilities experience in free-space know-how Adaptive Optics. The main objective communication group related to use atmospheric turbulence compensation improve performance Transportable Optical Ground Station (TOGS). This especially challenging when daytime...
