We report a quantum simulation of the deuteron binding energy on quantum processors accessed via cloud servers. We use a Hamiltonian from pionless effective fi eld theory at leading order. We
design a low-depth version of the unitary coupled-cluster ansatz, use the variational quantum eigensolver algorithm, and compute the binding energy to within a few percent. Our work is the fi rst
step towards scalable nuclear structure computations on a quantum processor via the cloud, and it sheds light on how to map scientifi c computing applications onto nascent quantum devices.
