Progress towards implementation of a quantum communication receiver satellite

Quantum communication via satellite based systems could enable quantum communications, such as Quantum Key Distribution, over truly global scales. Furthermore, they would allow us to perform quantum science experiments on entangled photons at scales and velocities not possible no the ground, which could be interesting in the quest towards understanding the boundary of quantum mechanics and space time. I will intrude the Canadian mission proposal called QEYSSAt (Quantum Encryption and Science Satellite) is considered as a possible microsatellite system, and will implement a quantum analyzer and detector in space.   I will present our progress towards implementing a prototype of the payload, as well as ground based test and analysis of the expected performance for quantum communication between ground and space.
