Basics of Quantum Computing

 The Quantum world is one of many mysteries. This world is governed by laws that don't seem to make any sense, but are proved to be true. What does quantum mean? And how is this connected to computing?  A close-up view of an IBM quantum computer. Source - Cnet.com Let's talk about each of these words individually first. Quantum, in layman's terms, means small. The mechanism or working of this subatomic world is governed by the rules of quantum mechanics. Let's understand some principles of quantum mechanics before talking about quantum computing. The quantum mechanical model of the atom, was the result of two important scientific advancements- Heisenberg's Uncertainty principle , and the dual behavior of matter proposed by de Broglie. To briefly explain these- de Broglie stated that every particle had wave nature, just as waves- like visible light- showed particle behavior. This dual behavior is particularly seen in smaller particles like electrons, and is negligib
