A system based on frontier mesoscopic semiconductor technology, able to performthe basic quantum operations needed for quantum computation, is proposed. Theelementary quantum bit (qubit) is defined as the state of an electron running along acouple of quantum wires coupled through a potential barrier with variable height and/or width. A proper design of the system, together with the action of Coulombinteraction of two electrons representing two different qubits, allows the implementationof basic one-qubit and two-qubit quantum logic gates. Numerical simulations confirmthe correctness of the hypothesis
