For starters Chinese researchers lie differently to how Western researchers lie.

Secondly it's exciting to see countries around the world do cutting edge research, like Japan bringing back the Ryugu samples.

Thirdly it's HN rules to copy the original article title.

Fourthly "Physicists challenge Google’s ‘quantum advantage’" implies the profession of Physicists are saying Google’s ‘quantum advantage’ is incorrect or something.

Ironically, this article is from December third, so the Chinese experiment being well known is only because past articles like this!

Titles shouldn't be editorialised without good reason, as per the guidelines. It's no more than that.
