  Recently, some authors have considered the quantum spectrum of black holes .
This consideration is extended to tachyonic black holes in a brane-anti-brane
system. In this study, black holes are constructed from two branes which are
connected by a tachyonic tube. As the branes come closer to each other, they
evolve and make a transition to thermal black branes. It will be shown that the
spectrum of these black holes depends on the tachonic potential and the
separation distance between the branes. By decreasing the separation distance,
more energy emerges and the spectrum of the black hole increases.
