Abstract: Terrestrial QKD channels can connect two links with a maximum distance of few hundred kilometres. In the case of fibre links, this is due to the signal attenuation in the fibre; in the case of free-space link the losses are due to atmospheric turbulence and absorption. Free-space optical terminals exploiting satellite-based relays are the only resource that can enable global scale quantum key distribution, since single photon propagation is for the main part in vacuum with no turbulence or absorption, and just… Show more

“…The first experimental single-photon exchange with a MEO sat at 7000 km of slant distance was realized in 2016 at MLRO [352]. The QKD links were modeled in previous studies [326,327]. A recent result addressing the photon exchange with two Glonass sats has supported the future possibility of QKD-enabled secure services for the GNSS satellites [353].…”

“…The extension of the QKD to secure links to long distance, to connect nodes of networks spanning large scales, including national, continental, planetary as well as space missions, was devised in feasibility studies more than a decade ago [323][324][325][326][327]. The extension to space of quantum communications (QC) was initially proposed in combination with experiments devoted to testing fundamental principles and resources of quantum information in the novel space context.…”

“…The criteria and analysis for the Quantum Key Distribution (QKD) in space has been analyzed in detail in a number of previous works and will not be repeated here. [4][5][6][7] On the other hand, we aim here also to point out the level of losses and signal-to-noise ration in the case of the intersatellite links. …”
