The local detection method: Dynamical detection of quantum discord with local operations
arXiv:1606.09049 · doi:10.1007/978-3-319-53412-1_14
Abstract
Quantum discord in a bipartite system can be dynamically revealed and quantified through purely local operations on one of the two subsystems. To achieve this, the local detection method harnesses the influence of initial correlations on the reduced dynamics of an interacting bipartite system. This article's aim is to provide an accessible introduction to this method and to review recent theoretical and experimental progress.
