"Even a relatively small quantum computer, one that had a few tens of thousands of qubits, could consider so many different values at once that it would be able to break all known [ed: RSA, D&H, ECC, AES-128] codes commonly used for secure Internet communication.”

Prof Seth Lloyd of MIT, MIT Review 2008

"Security and dependability issues typically go along with the life cycle of a technology.  The trend to first deploy a technology and later fix its problems – typically driven by economic motives – is gradually making way for security by design, resulting in improved security at the beginning of the life cycle."

"Unfortunately, the security issues of a technology near the end of its lifetime are typically overlooked.  The best known example is that of cryptographic keys and algorithms which may need to offer in some cases security for 50 to 100 years."
