    "abstract": "A basic property of distinguishability is that it is non-increasing under\nfurther quantum operations. Following this, we generalize two measures of\ndistinguishability of pure states--fidelity and von Neumann entropy, to mixed\nstates as self-consistent measures. Then we extend these two measures to\nquantum operations. The information-theoretic point of the generalized Holevo\nquantity of an ensemble of quantum operations is constructed. Preferably it is\nan additive measure. The exact formula for SU(2) ensemble is presented. With\nthe aid of the formula, we show Jozsa-Schlienz paradox that states as a whole\nare less distinguishable while all pairwise are more distinguishable in an\nensemble of quantum states, also occurs in an ensemble of quantum operations,\neven in the minimal dimensional case SU(2) ensemble.",
