Perez-Merchancano Física, Astronomía y Matemáticas Quantum dots Semiconductors Quantum computing In this work, the exchange energy J for a system of two laterally-coupled quantum dots, each one with anelectron, is calculated analytically and in a detailed form, considering them as hydrogen-like atoms, under theHeitler-London approach. The atomic orbitals, associated to each quantum dot, are obtained from translationrelations, as functions of the Fock-Darwin states. Our results agree with the reported ones by Burkard, Loss andDiVincenzo in their model of quantum gates based on quantum dots, as well as with some recent experimentalreports. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436520 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.36 |
