  • 755 Accesses

Abstract

Analytical solution of mutual information by square-root measurement for binary linear code is given. Applying the solution, we show properties of superadditivity in capacity by BCH codes with codeword length 15 and 31. Furthermore, we refer to codes almost achieving the quantum channel capacity.
