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 …

Satellite based quantum communications will enable long distances, or even global
quantum networking, of quantum optical signals. We give an overview on the activities …

The primary role played by communication in our society gives importance to the problem of
securely transmitting sensitive information. Quantum physics can be exploited to solve this …

Satellites offer the means to extend quantum communication and quantum key distribution
towards global distances. We will outline the proposed QEYSSat mission proposal, which …

A satellite-constellation based global quantum network could allow secure quantum
communication between remote users worldwide. Such a constellation could be formed of …

Rapid developments in quantum communication are paving the way forward for more
