In this paper, by utilizing the idea of stabilizer codes, we give some relationships between one local unitary representation of braid group in N-qubit tensor space and the corresponding entanglement properties of the N-qubit pure state, where the N-qubit stateis obtained by applying the braiding operation on the natural basis. Specifically, we show that the separability ofis closely related to the diagrammatic version of the braid operator. This may provide us more insights about the topological entanglement and quantum entanglement.
