Abstract

It is shown that no source encoding is needed in the definition of the capacity of a quantum channel for transmitting entanglement. This capacity bounds the ``protected subspace'' capacity. We find the capacity of the quantum erasure channel using these results, without relying on an unproven assumption as in an earlier paper.
