Let $\rho$ be a bipartite state. The quantities $E_{\chi,2}(\rho)$ and $E_{\kappa,2}(\rho)$ are the level-two quantities in the $\chi$- and $\kappa$-hierarchies, respectively, and…

Let $\rho=\rho_{AB}$ be a state. The quantities $E_{\chi,p}(\rho)$ are the $\chi$-quantities defined by the hierarchy at level $p$, and $E_{\kappa,p}(\rho)$ are the corresponding…
