Finite-order generalized R-matrix simulation conjecture

From papers

Let RX:CmCmCmCmR_X:\mathbb C^m\otimes\mathbb C^m\longrightarrow\mathbb C^m\otimes\mathbb C^m be a unitary (generalized) RR-matrix of finite order, used to define braid group representations by assigning

I(i1)RXI(ni1)I^{\otimes(i-1)}\otimes R_X\otimes I^{\otimes(n-i-1)}

to the braid generator σi\sigma_i. Finite-order RR-matrix simulation conjecture. Braiding quantum circuits arising from RXR_X can always be simulated classically. This claim concerns efficient classical simulation of braid-based quantum circuits and extends the motivation of the Knill–Gottesman theorem from Clifford circuits to generalized anyonic settings. The supplied text does not indicate whether the assertion has been proved or remains open.
