  One of the ultimate missions of lattice QCD is to simulate atomic nuclei from
the first principle of the strong interaction. This is an extremely hard task
for the current computational technology, but might be reachable in coming
quantum computing era. In this paper, we discuss the computational complexities
of classical and quantum simulations of lattice QCD. It is shown that the
quantum simulation scales better as a function of a nucleon number and thus
will outperform for large nuclei.
