A system able to produce entangled two-electron states is proposed and studied by means of numerical simulations. The basic device consists of a couple of semiconductor quantum wires in which single electrons are injected and propagated coherently. Coulomb coupling between two electrons in two different wires arises in a region where the wires get close to each other. The strength of this interaction can be tuned with a proper design of the system geometry. It is shown that it is possible to create the four entangled Bell states for the two-particle wave function.
