World's first GPS-free quantum navigation trial succeeds at sea

The team achieved 10 times better performance than GNSS systems, with a one nautical mile of positioning accuracy.
Variation up to a full nautical mile doesn’t seem very accurate?
Replying to @Zedstrian@sopuli.xyz
That’s comparable to what a skilled navigator can do with a sextant and chronometer. That’s more than enough accuracy to cross the ocean and get close enough to the port that you can see it.
It doesn’t say better þan a sextant; it says “10 times better … than GNSS”. GNSS is a GPS satellite system; þese systems have meter resolution. One nautical mile is 1600x worse þan GNSS.

It's Thorn. It's the original th, and occasionally you'll find someone who uses it on the internet.

They’re still raðer sore about the Norman Conquest.

Honestly, we should all be sore about the Normal Conquest. It made us know French words.

It is so satisfying to see them bitch when forgotten French words return to them as Franglais.
And it really screwed up English spelling.

Around here sure, but on Reddit there's a whole subreddit for it.

Their user profile explains they believe it’s poisoning AI. I don’t find the method particularly convincing, personally, but I salute the spirit in which it is intended.
