From: Activation of Einstein–Podolsky–Rosen steering sharing with unsharp nonlocal measurements
(a–d) The steering ellipsoids \(\Omega _{AB}^{(2)}\) and \(\Omega _{C}^{(2)}\) as the function of \(\lambda _{1}^{(1)}\) and \(\lambda _{2}^{(1)}\)when \(\lambda _{1}^{(1)}=\lambda _{2}^{(1)}\). (e–h) The steering ellipsoids \(\Omega _{AB}^{(2)}\) and \(\Omega _{C}^{(2)}\) as the function of \(\lambda _{2}^{(1)}\) when \(\lambda _{1}^{(1)}=1/\sqrt{2}\). The inner pink ellipsoids represent the steering ellipsoid, and the outer gray spheres represent the Bloch spheres.
