Measures and dynamics of entangled states
Florian Mintert, Andre R. R. Carvalho, Marek Kus, Andreas Buchleitner
abstract: We develop an original approach for the quantitative characterisation of the
entanglement properties of, possibly mixed, bi- and multipartite quantum states
of arbitrary finite dimension. Particular emphasis is given to the derivation
of reliable estimates which allow for an efficient evaluation of a specific
entanglement measure, concurrence, for further implementation in the monitoring
of the time evolution of multipartite entanglement under incoherent environment
coupling. The flexibility of the technical machinery established here is
illustrated by its implementation for different, realistic experimental
scenarios.
