Hmm, that doesn't sound right to my ear.

They've loudly assumed it is possible.

c.f. Their focus has been on incentivizing private actors to do post-quantum algorithms, yesterday.

Do you have more info on why they'd ban import of it? Seems like an obviously wrong strategy to combat it.

Aren’t these export controls rather than import controls? That is, if a company in their bloc does succeed at developing cryptographically-relevant quantum computers, they’d just as soon that company not sell that tech on to the adversary?

As you said, they’ve loudly assumed it’s possible—so wouldn’t it make sense for them to draw a line in the sand now, before the horse has bolted, to indicate where the “now it’s a national security matter” threshold lies?
