Submission + - Who is afraid of the big bad Quantum Computer? (

quax writes: Whenever Quantum Computing is dragged out to get some mainstream exposure it is the same old story: If we finally get these powerful machines then the end of all encryption is here and the sky is falling.

This article makes the case that there is much more to Quantum Computing than that, and that all the hand-wringing is not only pre-mature but also rather silly. Current quantum computing devices cannot defeat our standard encryption yet, but are at a point where they can already be a valuable new computing resource. On the other hand when considering how modern cryptography works, and when taking into account the progress made on Quantum Cryptography, the often repeated threat from Quantum Computers to the privacy of a encrypted data appears to be completely overblown.
