The role of the ℓ1-norm in the Yang–Baxter system has been studied through Wigner's D-functions, where ℓ1-norm means ∑i|Ci| for |Ψ⟩ = ∑iCi|ψi⟩ with |ψi⟩ being the orthonormal basis. It is shown that the existing two types of braiding matrices, which can be viewed as particular solutions of the Yang–Baxter equation (YBE) with different spectral parameters can be unified in the 2D YBE. We prove that the maximum of the ℓ1-norm is connected with the maximally entangled states and topological quantum field theory with two-component anyons, while the minimum leads to the deformed permutation related to the familiar integrable models.
