Lockheed Martin wants to use a quantum computer to develop radar, aircraft systems, article.
I thought that quantum computing was still only theoretical, but it seems they have working computers. Though limited and very expensive.
The idea of a computer which is not purely dualistic (either one or zero, either yes or now), is a bit mind-boggling. But then this article says "quantum computing is more probabilistic, also allowing a combination of zero and one to simultaneously answer many questions with quantum bits of information", so maybe it's not as different as one might think.
