Depends what you're ascribing to it.

Will it break encryption? Yes. That's been well understood since the 90's.

Will it help solve certain specific physics problems, including practical ones? Also yes.

Will it do literally anything else? Maybe, maybe not. Honestly, even calling it a "computer" is misleading unless you're an expert. For layman purposes it's more like an electron microscope or ultracentrifuge. Very useful for a very narrow set of tasks.
