Quantum discord for multiqubit systems

We evaluate analytically the quantum discord for a large family of multiqubit states. It is interesting to note that three-qubits and five-qubits same, as two-qubits six-qubits. discover this states can be concluded into three categories. The level surfaces in categories shown through images. Furthermore, we investigated dynamic behavior under decoherence. For odd partite systems, prove frozen phenomenon doesn't exist phase flip channel, while it found even systems.
