Corrigendum: Concise and tight security analysis of the Bennett–Brassard 1984 protocol with finite key lengths (2012 New J. Phys. 14 093014)

Abstract

The paper (Hayashi M and Tsurumaru T 2012 New J. Phys. https://doi.org/10.1088/1367-2630/14/9/093014 https://doi.org/10.1088/1367-2630/14/9/093014 ) contains an error at the definition of g _t ( x ) in section 5.3 while g _t ( x ) is used for the second order asymptotic expansion for the sacrifice bit. This corrigendum corrects this error and shows its derivation.
