We recast Selinger's CPM-construction of completely positive maps [11] as an axiomatization of maximally mixed states. This axiomatization also guarantees categories of compl...

Quantum 2-party cryptography differs from its classical counterpart in at least one important way: Given blak-box access to a perfect commitment scheme there exists a secure 1−2...
