  We report the experimental realization of the ''active'' quantum
teleportation (QST) of a one-particle entangled qubit. This demonstration
completes the original QST protocol and renders it available for actual
implementation in quantum computation networks. It is accomplished by
implementing a 8m optical delay line and a single-photon triggered fast
Electro-Optic Pockels cell. A large value of teleportation ''fidelity'' was
attained: F = (90 +/- 2)%. Our work follows the line recently suggested by H.
W. Lee and J. Kim, Phys. Rev. A 63, 012305 (2000) and E.Knill, R.Laflamme and
G.Milburn Nature 409: 46 (2001).
