The TEE for the square lattice with strength of external fields g. Red circles represent results from the microwave experiments. Black squares are theoretic results of TEE obtained from the corresponding MESs. Inset: when the model belongs to Z2 topological order, the long-range entanglement in the MES indicated as the TEE is γ  = ln2; the model belongs to the trivial phase when the external field becomes strong and the TEE is γ = 0. Error bars are defined as s.d. Source data are provided as a Source Data file
