Don't think too much, at present of quantum communication, actually refers to "quantum secret communication", in which traditional do quantum key communications, which is quantum key, encrypt plaintext cipher, put the cipher text with the traditional radio or optical fiber to send out, so the quantum technology is a kind of encryption technology, say a bit more accurate, is just a kind of secure key distribution of the encryption technology, so, means of transport are all the same, what do you think can have a very big change!
