Abstract
We discuss characteristic properties of Quantum Darwinism (QD) involving pure decoherence, dissipation and dephasing. In particular, we reconstruct and derive the structure of the corresponding dissipative dephased attractor spaces of our random unitary qubit-model of QD and investigate whether QD appears with respect to evolution based on non-Controlled-NOT (non-CNOT) unitary operations. We identify those attractor space structures that allow the most efficient storage of classical information about a system into its environment. Furthermore, we conclude that CNOT-type unitary operations appear to be well suited copy-machines when it comes to efficiently store the information about a system's pointer basis into the environment.
