  An electron teleportation protocol, inspired by the scenario by Bennett et
al., is proposed in a mesoscopic set-up. A superconducting circuit allows to
both inject and measure entangled singlet electron pairs in an array of three
normal quantum dots. The selection of the teleportation process is achieved in
the steady state with the help of two superconducting dots and appropriate
gating. Teleportation of the electron spin is detected by measuring the
spin-polarized current through the normal dot array. This current is perfectly
correlated to the pair current flowing inside the superconducting circuit. The
classical channel required by Bennett's protocol, which signals the completion
of a teleportation cycle, is identified with the detection of an electron
charge in the superconducting circuit.
