This is the impression they want you to have. There are a few caveats:
* You need a direct connection with a limit in length. This means effectively you can't have wifi, mobile internet or anything like that. You also probably can't use it to have a connection between the US and Europe. Calling that a "quantum internet" is... only possible if you have no idea what the term "internet" means.
* You need an existing authenticated channel or be vulnerable to man in the middle attacks. The quantum key distribution schemes always assume this already exists, but never care to explain where they got it from.
- dTal 8y ago>You need an existing authenticated channel or be vulnerable to man in the middle attacks Isn't this theoretically unavoidable for all forms of encryption? You need some way of distinguishing your intended communication partner, because the best that any protocol could do is establish a secure link with whoever is on the other end of the line.
