Final state of a black hole is studied by taking into account a general unitary evolution of a black hole matter state. It is found that the mixedness decreases under general unitary transformation when the initial matter state was in mixed state and the mean fidelity at the evaporation is smaller than the fidelity of the quantum teleportation by the factor of inverse square of the number of states of a black hole. The change of entanglement Alice-Bob pair at evaporation is also studied by calculating the entanglement fidelity and eigenvalues of the partial transposed block density matrix. We assumed that Alice fell onto the black hole when the hole was formed while Bob is maintaining the safe distance from the black hole. It is found that the entanglement fidelity is inversely proportional to the square of the Hilbert space dimension N and the entanglement can survive the evaporation process.
