摘要：

We study mixed anomaly between G(1) and G(2) of one-form finite symmetry G(1) x G(2) in 3d Chern-Simons theories. We assign a quantum entanglement structure to two linked G-symmetry lines (Wilson loops) and compute the entanglement entropy S[G]. We find a measure of the mixed anomaly by computing S[G(1) x G(2)] - S[G(1)] - S[G(2)].
