Quantum Computers

Quantum mechanics is a subject that has the strange property of simultaneously being logically rigorous and yet completely counterintuitive. So much so, that even a towering intellect like Einstein could never bring himself to accept its principles even though products based on the same exist all around us. The earliest oddity, identified by Schrodinger, one of the founders of quantum mechanics is about a hypothetical cat that is neither dead nor alive until someone actually observes it. A similar oddity is that of quantum entanglement, where the behaviour of one particle is instantly affected by the behaviour of another particle, however distant it may be -- an example of “spooky” action-at-a-distance. Explaining these phenomena is beyond the scope and temerity of this article and so the reader would have to accept them here in good, almost religious, faith and carry on with the belief that such phenomenon has been observed and explained by scientists under the most rigorous experime...
