Figure 4From: Secret key rate bounds for quantum key distribution with faulty active phase randomizationSecret key rate in logarithmic scale versus the overall system loss when the phases lie in the intervals \(\theta _{k}\pm \delta _{\text{max}}\) and the function \(g(\theta )\) is unknown, as a function of the total number of random phases N selected by Alice and the value of \(\delta _{\text{max}}\)Back to article page
