Secure quantum communication is very tricky, and afaik the Chinese
didn't do that, they just did some entangled photon measuring.
First, the non-cloning

Albert Einstein called it "spooky action at a distance". He hated the concept
of quantum mechanics, saying "God does not play dice with the Universe".
Unfortunately, Einstein was quite wrong.
The idea is that pairs of photons can be generated and can go virtually any
distance, and then a
I quote the main title of the article:
"Scientists in China managed to exchange a crypto key at a distance of over
1,000 kilometers"
Wow!
How can they do that?
