Abstract

The extremum values of quantum $$\alpha $$ -fidelity under unitary orbits of quantum states are explicitly derived by applying rearrangement inequalities, matrix trace inequalities, and theory of majorization. Furthermore, the $$\alpha $$ -fidelity is successfully verified to go through the whole closed interval, which works from the minimum value to the maximum value.
