  An extension of the Variational Quantum Eigensolver (VQE) method is presented
where a quantum computer generates an accurate exchange-correlation potential
for a Density Functional Theory (DFT) simulation on classical hardware. The
method enables efficient simulations of quantum systems by interweaving
calculations on classical and quantum resources. DFT is implemented on
classical hardware, which enables the efficient representation of and operation
on quantum systems while being formally exact. The portion of the simulation
operating on quantum hardware produces an accurate exchange-correlation
potential but only requires relatively short depth quantum circuits.
