Performance of the RAQST protocol for mixed states. a Infidelity vs. N with different tomography protocols for state ρ = ρ W (0.997), which has purity Tr(ρ 2) = 0.9955. Each point is averaged over 200 realizations. Error bars are the standard deviation of the average. b Infidelity vs. different purity with different tomography methods for Werner states in (5). The total number of copies for each state is N = 104. Each point is averaged over 1000 realizations
