Definitely not a quantum expert, but I have a feeling that news like this have been happening for more than a decade, without anything usable.
It's great funding for physics research. I don't care if it's useless, it beats spending on politics and surveillance
There's also the fact that the road to useful is littered with useless, because how else would you make progress?
You could do what evolution does, and require that every version be useful. But evolution seems to require an awful lot of trial and error.
Evolution requiring that every version is useful seems a (significant) oversimplification.
