    "abstract": "We introduce a Werner-like mixture [R. F. Werner, Phys. Rev. A {\\bf 40}, 4277\n(1989)] by considering two correlated but different degrees of freedom, one\nwith discrete variables and the other with continuous variables. We evaluate\nthe mixedness of this state, and its degree of entanglement establishing its\nusefulness for quantum information processing like quantum teleportation. Then,\nwe provide its tomographic characterization. Finally, we show how such a\nmixture can be generated and measured in a trapped system like one electron in\na Penning trap.",
