Excellent and awesome news- thanks! I find I prefer the writeup from Scientific American, by the way.

ETA: After looking at my comment, I had to check and make sure I wasn't a spambot. Don't know how to sound less stilted, though.

Thanks for that link. The one I submitted is definitely not perfect, in particular it strongly implies a violation of the No Comminication Theorem.

Great to see QM confirmed at macroscopic scale, ruling out "collapse" a bit more, but... the article way of saying things does unsettle me, as you say.

Formulations like "teleport bits of light" and comparison to Star Trek teleportation in the link on it make people think you can violate the No Communication Theorem. And things like "the research could help develop faster computers called photonic processors, relying on quantum effects" (semiconductors already rely on quantum effects, sure photonic processors would be faster than ours, but ours already "rely on quantum effect", and so do laser, it's not just futurist tech, it's actual tech that uses QM) just are ways to sound sensational while risking people to make wrong images in their head.

I don't have the background to know whether this was mind-blowingly-awesome or just mildly neat, and I'm surprised by the lack of comments either saying "OMGWOW!" or "This isn't really that big a deal"
