    • The transformation need be unitary only on the parallel subspace, and not on the whole Hubert space. Let |ψ| belong to the Hubert space H. Then the parallel space P is defined to be the subspace of ℋ⊗ℋ Ji that is spanned by all vectors of the form |ψ|ψ proving the no deleting theorem, that is, to prove the nonexistence of a transformation that achieves (2), we need only assume that the transformation is unitary on the subspace P.

    • This machine was also considered in Ref. [29] for the purpose of what was called "broadcasting of entanglement." However, note here that the concept of broadcasting of entanglement imposes some separability requirements (see [29]) on the output state at ABA'B'. These separability constraints are not required in our considerations. It is therefore conceivable that better local cloning machines than the one in Eq. (33) can be obtained, at least for mixed entangled states.
