Feasibility Analysis for Quantum Key Distribution between a LEO Satellite and Earth
TLDR
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 a small part of the path is through the atmosphere.

Link budget and background noise for satellite quantum key distribution
TLDR
We study the feasibility of QKD from low-Earth orbit satellites to Earth during night time; we analyze the link attenuation and the signal to noise ratio (SNR) for its visibility time. Expand

On the Polarization Analysis of Optical Beams for Use in Quantum Communications between Earth and Space
TLDR
We address the transformation of the polarization state of single photons during the transmission along a Space channel and the measures to correct them in order to accomplish Quantum Communication (QC) between Space and Earth. Expand

Experimental studies toward the Quantum Communications with orbiting terminals
Realization of Quantum Communications in Space requires a deep understanding of issues including link-budget, turbulence mitigation and single-photon terminal synchro-nization. Here we report onExpand
Quantum communication channels between earth and space and space to earth
The work presented in this thesis, on the topics of global quantum network, is the result of a set of research activities done at the CNR-IFN Luxor laboratory over these three years. The main goalExpand
Intersatellite quantum communication feasibility study
The shift in the Communication paradigm from the bit to the qubit is increasingly exploited in terrestrial long range links and networks, with strong potentials in secure communications, quantumExpand
