We generalize our results in paper I in this series to quantum channelsbetween general v. Neumann algebras, proving the approximate recoverability ofstates which undergo a small change in relative entropy through the channel. Tothis end, we derive a strengthened form of the quantum data processinginequality for the change in relative entropy of two states under a channelbetween two v. Neumann algebras. Compared to the usual inequality, there is anexplicit lower bound involving the fidelity between the original state and arecovery channel.
