You've probably heard peopleā€”including usā€”banging on about quantum computers for a long ol' time. But that doesn't necessarily mean you know exactly how they work. Fortunately this video is here to help.

It goes straight from the basic of how quantum bitā€”a qubitā€”can carry more information than a normal bit, right the way up to how that fact can be exploited to achieve mind-blowing computational power. Get watching. [YouTube]
