From: Negativity vs. purity and entropy in witnessing entanglement
Plot showing percentages of 60-dimensional joint systems sampled according to the uniform-purity ensemble, whose entanglement was witnessed by comparing different forms of joint and marginal entropies, and by the negativity of the partial transpose. These systems were bipartitioned into subsystems of dimensions \(D_{A}\) and \(D_{B}\) respectively, such that \(D_{A}D_{B}=60\). Starting with \(10^{6}\) random diagonal density matrices, different random unitaries were performed for each possible bipartition to generate the full ensemble of density matrices analyzed here. The entanglement-success percentages are plotted as a function of \(D_{B}\). The vertical axis denotes the different entanglement witnesses used, and in particular, that we are conditioning on subsystem B.
