Quantum Computing Not an Imminent Threat To Public Encryption

Posted by Soulskill on from the in-search-of-schrodinger's-catastrophe dept.

Bruce Schneier's latest blog entry points out an interesting analysis of how quantum computing will affect public encryption. The author takes a look at some of the mathematics involved with using a quantum computer to run a factoring algorithm, and makes some reasonable assumptions about the technological constraints faced by the developers of the technology. He concludes that while quantum computing could be a threat to modern encryption, it is not the dire emergency some researchers suggest.

    Your data is both encrypted and unencrypted at the same time, only reverting to one state or the other when you observe it and collapse the waveform. There is also, if I read this correctly, some chance that it will turn into a cat.

    Hope that clears it up for you...
