Abstract or Description

We investigate the entanglement, CHSH nonlocality, fully entangled fraction and symmetric ex-tendibility of two-qubit states that have a single maximally mixed marginal. Within this set of states, the steering ellipsoid formalism has recently highlighted an interesting family of so-called ‘maximally obese’ states. These are found to have extremal quantum correlation properties that are significant in the steering ellipsoid picture and for the study of two-qubit states in general.
