http://en.wikipedia.org/wiki/Post-quantum_cryptography http://en.wikipedia.org/wiki/Post-quantum_cryptography My understanding is that schemes that would be resistant to quantum attacks are much less efficient, and have more negative tradeoffs, than the systems in use today. Speed is an important property for a most cryptography, so few people would adopt such a system until the threat seems more pressing.
