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.
That way a satellite would be preloaded with hundreds of "hidden" secret keys and one of them would be available for encrypting only when it would be decided on the ground. A quantum twist to Merkle's puzzles.
I am not convinced by this kind of quantum cryptography. I am sure it would be possible to crack it, because all cryptography proposals are overly complexifying a little aspect of a much larger problem, and someone just look at another aspect of the problem and easily defeats the proposed cryptography scheme.
It is a pattern that we seen an incredible number of times, when do people will recognise it and adopt a more humble, honest and safer way to implement security?
Indeed I am yet another random guy on Internet, I am not versed in quantum cryptography, and I did not work on cryptography since a long time. But on the anecdoctical side, 12 years ago I had to work on identity/security and at that time when I told my colleagues that public cryptography was no more safe, they were baffled. For them it was pure non-sens, yet I could crack (factor in prime numbers) simple keys on my little laptop and RSA stopped a few years later their famous RSA challenge [0]...
