At my school, the so-called "gifted and talented" leader/teacher, Mr Salt (who reminds me of Father Christmas), while i was helping to teach 10-year-olds quadratic equations, (they are smart-almost as fast as me, and im 15), told us that two scientists have created the first quantum computer. He also said that it is 1000 times more powerful than the most powerful "normal" computer (I presume this is the IBM machine built, which the processor runs at 400Ghz at room temperature) but only lasts for one second, is this true, or have I, once again, got this wrong?
