ResumoWe report a quantum simulation of the deuteron binding energy on quantum processors accessed via cloud servers. We use a Hamiltonian from pionless effective field 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 first step towards scalable nuclear structure computations on a quantum processor via the cloud, and it sheds light on how to map scientific computing applications onto nascent quantum devices.Received 12 January 2018DOI:https://doi.org/10.1103/PhysRevLett.120.210501© 2018 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasNuclear structure & decaysQuantum simulationPropertiesA ≤ 5Nuclear bindingNuclear PhysicsQuantum Information
