The minimal surface of the entanglement wedge C^1_A is the entanglement entropy of A in CFT. The insertion of a brane C^n_A induces a back-reaction on the bulk. If no back-reaction is present, the area of C^n is the same of the non-backreaction area of C^1_A so back-reaction is due to the sensitivity to the Renyi index n of the brane. We show in arXiv:2403.07056 that the holographic dual of such back-reaction in CFT is the non-local magic or stabilizer entropy.
