I thought as much. The article said they were using entangled particles,
which AFAIK would only transmit the information. However , I remember seeing
a report on a teleportation device IBM had created which had successfully
teleported a single photon (they used the entangled particles to find it's
location at one end, put a photon at the exact same location the other end
and then destroy the original photon.)
