Local NOT operations convert entanglement sudden death to asymptotic decay for genuine multipartite concurrence in small multipartite systems under amplitude damping, while teleportation fidelity preservation requires flipping all qubits in some cases and allows use of biseparable states in GHZ CQT.

Decoherence Mitigation with Local NOT Gates in Multipartite Systems
Local NOT operations convert entanglement sudden death to asymptotic decay for genuine multipartite concurrence in small multipartite systems under amplitude damping, while teleportation fidelity preservation requires flipping all qubits in some cases and allows use of biseparable states in GHZ CQT.
