I read about this in the NYT, so off to Wikipedia I went. Still don’t understand quantum physics.
I do understand that quantum computing might just sidestep Moore’s Law. And there are some worrisome aspects to having the ability to crunch large amounts of data beyond what we can do now, as well as the good side.
I find it really hard to accept that something that may happen to photons can scale up to be applicable in real life. (Then again: we’re probably all screwed if it does. For one thing, kiss any encrypted Internet data goodbye: a quantum computer allegedly could crack RSA or any other tough cypher.)
