A hazard of open quantum dynamics: Markov approximations encounter map domains
Thomas F. Jordan, Anil Shaji, E. C. G. Sudarshan
A Markov approximation in open quantum dynamics can give unphysical results when a map acts on a state that is not in its domain. This is examined here in a simple example, an open…
Entanglement increase from local interactions with not-completely-positive maps
Thomas F. Jordan, Anil Shaji, E. C. G. Sudarshan
Simple examples are constructed that show the entanglement of two qubits being both increased and decreased by interactions on just one of them. One of the two qubits interacts wit…
Completely Positive Maps and Classical Correlations
César A. Rodríguez-Rosario, Kavan Modi, Aik-meng Kuah +2
We expand the set of initial states of a system and its environment that are known to guarantee completely positive reduced dynamics for the system when the combined state evolves…
