The more interesting question may be what innovation was achieved in performing the experiment, mainly I assume, in controlling and measuring the large number of photons accurately. Hints on those seem to be Fig. 2 [1].

In the spirit of sensationalizing "China" and "supremacy", does anyone know if this technology is relevant to some Star Wars weaponry for example?

It's not control of individuals photons (that would be boson sampling), but gaussian pulses. Still a tour-de-force of a demonstration, but actual practical implications are very limited.
