Fig. 8: One-way information reconciliation (IR) efficiency.
From: Finite key performance of satellite quantum key distribution under practical constraints

We estimate \({{{{{{{\boldsymbol{{f}}}}}}}_{{{{{{{{\rm{EC}}}}}}}}}^{{{{{{{{\rm{est}}}}}}}}}}}\) as a function of satellite overpasses with maximum elevation angle \({\theta }_{\max }\) for different memory buffers mb. For data representative of current engineering efforts, \({f}_{{{{{{{{\rm{EC}}}}}}}}}^{{{{{{{{\rm{est}}}}}}}}}\) remains larger than 1.05, which is the lowest quoted achievable efficiency in the literature and is illustrated by the grey region corresponding to optimistic efficiencies.
