  Light-cone distribution amplitudes (LCDAs) are essential nonperturbative
quantities for theoretical predictions of exclusive high-energy processes in
quantum chromodynamics (QCD). We demonstrate the prospect of calculating LCDAs
on a quantum computer by applying a recently proposed quantum algorithm, with
staggered fermions, to the simulation of the LCDA in the (1+1)-dimensional
Nambu-Jona-Lasinio (NJL) model on classical hardware. The agreement between the
result from the classical simulation of the quantum algorithm and that from
exact diagonalization justifies the proposed quantum algorithm. We find that
the resulting LCDA in the NJL model exhibits features shared with the LCDAs
obtained from QCD.
