Performance of the superadditivity task for 30 channel uses. The gain in transmission rate is plotted as a function of the average photon number per use of the channel (\({\bar{n}}\)) and for different values of the noise correlation parameter (\(\phi\)). Additional parameters are chosen as follows: \(m_\text {io}=m_\text {mem}=1\), \(N={\bar{n}}/3\).
