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

We study entanglement dynamics of pure three-qubit Greenberger–Horne–Zeilinger-type entangled states when one, two or three qubits are 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 completely described by the evolution of the entangled states in single-sided channels.
