We examine the system-reservoir dynamics of classical and quantum correlations in the decoherence phenomenon within a two-qubit composite system interacting with two independent environments. The most common noise channels (amplitude damping, phase damping, bit flip, bit-phase flip, and phase flip) are analyzed. By analytical and numerical analyses we find that, contrary to what is usually stated in the literature, decoherence may occur without entanglement between the system and the environment. We also show that, in some cases, the bipartite quantum correlation initially present in the system is completely evaporated and not transferred to the environments.

• The classical-quantum boundary for correlations: Discord and related measures (2011, methodology): “(Maziero et al., 2010c) take a model of two noninteracting qubits subject to independent noise channels, and consider the evolution and transfer of classical and quantum correlations across different partitions of the system (intra-system, system-environment, and environment-environment).”
