    "abstract": "In quantum operations, probabilities characterise both the degree of the\nsuccess of a state transformation and, as density operator eigenvalues, the\ndegree of mixedness of the final state. We give a unified treatment of\npure-to-pure state transformations, covering both probabilistic and\ndeterministic cases. We then discuss the role of majorization in describing the\ndynamics of mixing in quantum operations. The conditions for mixing enhancement\nfor all initial states are derived. We show that mixing is monotonically\ndecreasing for deterministic pure-to-pure transformations, and discuss the\nrelationship between these transformations and deterministic LOCC entanglement\ntransformations.",
