Maybe I have a wrong notion of what is an "object" but in this context, I would at least expect it has a non zero mass.
The article is simply about entanglement of photons:
"To perform the experiment, the Chinese team created entangled pairs of photons ... They then beamed one of these photons ... They kept the other photon on the ground"
Using an ad hoc 3D printer to send a copy of a virus hundred kilometers away, as in Craig Venter's book "Life at the speed of light", would be a much greater achievement.
