Determinant computation is equivalent to matrix powering
$begingroup$
It has been claimed in this paper (page 2 last paragraph) that Matrix powering is equivalent to determinant computation.

Does anybody why is this the case?

It states that matrix powering is computationaly equivalent to computation.
From another angle, Coppersmith–Winograd algorithm for matrix multiplication has complexity $mathcal O(n^{2.373})$ and the same complexity is for determinant computation by fast multiplication.
The result comes from Triangularization and inversion via fast multiplication by James R. Bunch and John E. Hopcroft

Look at the paper by Stephen Cook (numbered $[3]$ in the references of the paper you have mentioned). There, in proposition $5.2$ in page $13$, he shows the "computational equivalence" between matrix powering and determinant computation (and other problems).

Perhaps you should add the paper’s title, and if possible, a link.
