Efficient mutual magic and magic capacity with matrix product states
Stabilizer Rényi entropies (SREs) probe the non-stabilizerness (or "magic") of many-body systems and quantum computers. Here, we introduce the mutual von-Neumann SRE and magic capacity, which can be efficiently computed in time $O(N\chi^3)$ for matrix product states (MPSs) of bond dimension $\chi$....
