Fig. 5: Loss and key rates for a three-satellite network passing above ground stations d = 4400 km apart.
From: Simulating quantum repeater strategies for multiple satellites
The colors match the relative positions of the satellites in Fig. 3, such that when SC is exactly in the middle point between the ground stations SA will be at 0% (blue), 10% (orange), 20% (pink), or −10% (gray) of the total ground distance d. a Combined atmospheric and diffraction loss between A and SC (dashed lines) and along the whole optical path (solid lines). b The obtainable asymptotic key rate for Scenario 1 at points along the orbit if satellites were static at these positions.
