Introducing quantum computing

Quantum computing isn't a subject that is as common as learning algebra or reading some of the literary classics. However, for most scientists and engineers or any other field that includes studying physics, quantum computing is part of the curriculum. For some of us who don't quite recall our studies in physics, or have never studied it, need not worry, as this section aims to provide you with information that will either refresh your recollection on the topic or at least perhaps help you understand what each of the principles used in quantum computing mean. Let's start with a general definition of quantum mechanics.

Quantum mechanics, as defined by most texts, is the study of nature at its smallest scale – in this case, the subatomic scale. The study of quantum mechanics is not new. Its growth began in the early 1900s by many physicists, whose names still chime in many of the current theories and experiments. The names of such...
