Entanglement dynamics of three-qubit states in many-sided noisy channels

Abstract

We study entanglement dynamics of pure three-qubit Greenberger-Horne-Zeilinger-type (GHZ-type) entangled states when one, two or three qubits being subjected to general local noise. Employing a lower bound for three-qubit concurrence as an entanglement measure, we show that for some many-sided noisy channels the entanglement dynamics can be complete described by the evolution of the entangled states in single-sided channels.
