  We present a quantum algorithm for simulation of quantum field theory in the
light-front formulation and demonstrate how existing quantum devices can be
used to study the structure of bound states in relativistic nuclear physics.
Specifically, we apply the Variational Quantum Eigensolver algorithm to find
the ground state of the light-front Hamiltonian obtained within the Basis
Light-Front Quantization framework. As a demonstration, we calculate the mass,
mass radius, decay constant, electromagnetic form factor, and charge radius of
the pion on the IBMQ Vigo chip. We consider two implementations based on
different encodings of physical states, and propose a development that may lead
to quantum advantage. This is the first time that the light-front approach to
quantum field theory has been used to enable simulation of a real physical
system on a quantum computer.
