  If a photon interacts with a member of an entangled photon pair via a
so-called Bell-state measurement (BSM), its state is teleported over
principally arbitrary distances onto the second member of the pair. Starting in
1997, this puzzling prediction of quantum mechanics has been demonstrated many
times; however, with one very recent exception, only the photon that received
the teleported state, if any, travelled far while the photons partaking in the
BSM were always measured closely to where they were created. Here, using the
Calgary fibre network, we report quantum teleportation from a
telecommunication-wavelength photon, interacting with another telecommunication
photon after both have travelled over several kilometres in bee-line, onto a
photon at 795~nm wavelength. This improves the distance over which
teleportation takes place from 818~m to 6.2~km. Our demonstration establishes
an important requirement for quantum repeater-based communications and
constitutes a milestone on the path to a global quantum Internet.
