Quantum steering on IBM quantum processors

We use contemporary quantum computers to experimentally investigate steering of an open system by measurements on its environment. On three IBM processors we distinguish a qubit as the and perform pairwise interactions with multiple environment ancillas, following collision model approach. Different measurement strategies ancillas lead different state ensembles system, which are reconstructed employing tomography. The amount within resulting assemblages is quantified help semidefinite program. successfully observe presence in our experimental simulations can discriminate performance qualities noise levels selected devices.
