Abstract : The program of the grant (evolution and survival of quantum entanglement) was advanced by extending to open-system relevance an important lead reported earlier (provided by Jaynes-Cummings closed-system modelling). We report success in tracking the movement of quantum entanglement. Reversals of the entanglement sudden death (ESD) effect are now also open to study in the case of revival effects in coherent-state quantum fields. A new finding is the discovery of a way to hide entanglement completely (reducing concurrence to effectively zero values) for extended periods, but then recover it with manageable loss at later times on a managed schedule. An extended account of work done, with accompanying papers, is attached.
