Recently, some quantum algorithms have been implemented by quantum adiabatic evolutions. In this Letter, we discuss the accurate relation between the running time and the distance of the initial state and the final state of a kind of quantum adiabatic evolutions. We show that this relation can be generalized to the case of mixed states. © 2006 Elsevier B.V. All rights reserved.
