Reply to Comment on `Connection between entanglement and the speed of quantum evolution´ and on `Entanglement and the lower bounds on the speed of quantum evolution´

Chau\'s Comment deals with the properties exhibited by a particular set of two-qubit states in connection with entanglement and the quantum evolution of some low-dimensional composite systems. However, there is an important aspect of the previously mentioned two-qubit states and of the role they play in relation with the \"speed\" of quantum evolution that was not mentioned by Chau and deserves to be pointed out: for the two-qubit system under consideration, these states require the longest possible absolute time to evolve to an orthogonal state.
