Quantum computing and Bitshares

[santaclause102]

This https://medium.com/quantum-bits/how-secure-will-our-data-be-in-the-post-quantum-era-6a7f444ce7d5#.dp6gjc95i and the IOTA brains (http://cointelegraph.com/news/115508/iota-a-blockchain-less-gasp-token-for-the-internet-of-things) say: " Every piece required for a quantum computer to exist has been experimentally demonstrated. It’s now an engineering challenge" (medium blog).

Would we simply replace all quantum cryptography in graphene as soon as evidence shows that the dawn of the quantum computer has arrived? Another guess (tell me please if that is correct): CNX has decided to go the simple and historically prven way of known cryptography and thinks that bigger targets would be hit first giving us time to upgrade.
