    "abstract": "In this work, the exchange energy J for a system of two laterally-coupled\nquantum dots, each one with an electron, is calculated analytically and in a\ndetailed form, considering them as hydrogen-like atoms, under the\nHeitler-London approach. The atomic orbitals, associated to each quantum dot,\nare obtained from translation relations, as functions of the Fock-Darwin\nstates. Our results agree with the reported ones by Burkard, Loss and\nDiVincenzo in their model of quantum gates based on quantum dots, as well as\nwith some recent experimental reports.",
