Fig. 7

Shown are: (a) the secret key rate in secret bits per entanglement generation attempt, (b) the quantum bit error rate (QBER) in the X and Z bases (c) the average number of attempts necessary for one successful end-to-end entanglement generation. Each data point is obtained using 10.000 (EIT) or 30.000 (AFC) successful attempts at generating entanglement between the end nodes. Solid lines are fits. Note that for the secret key plot we use logarithmic scale with added 0 at the origin of the axes. Error bars denote standard deviation and are symmetrical.
