Frozen and Invariant Quantum Discord under Local Dephasing Noise
arXiv:1707.06442 · doi:10.1007/978-3-319-53412-1_16
Abstract
In this chapter, we intend to explore and review some remarkable dynamical properties of quantum discord under various different open quantum system models. Specifically, our discussion will include several concepts connected to the phenomena of time invariant and frozen quantum discord. Furthermore, we will elaborate on the relation of these two phenomena to the non-Markovian features of the open system dynamics and to the usage of dynamical decoupling protocols.
