Quantum theory is one of the most successful theories that have influenced the course of scientific progress during the twentieth century. It has presented a new line of scientific thought, predicted entirely inconceivable situations and influenced several domains of modern technologies. There are many different ways for expressing laws of science in general and laws of physics in particular. Similar to physical laws of nature, information can also be expressed in different ways. The fact that information can be expressed in different ways without losing its essential nature, leads for the possibility of the automatic manipulation of information. Quantum computing is a study area that focuses on developing computers based on the properties of “quantum theory” & “quantum physics”. Quantum theory defines the behavior & nature of energy and matter on the “atomic” and “subatomic” levels also known as the quantum levels. A quantum computer is a computational device that utilizes the phenomena of quantum mechanics with its quantum properties to structure & process data. A large-scale quantum computer is capable of performing operations in exponentially enormous speed compared to a classical computer. Development of such computers is considered a massive leap for mankind in computing abilities with huge performance gains for simulations or brute force for example. All ways of expressing information use physical system, spoken words are conveyed by air pressure fluctuations: “No information without physical representation”. Quantum computers are not meant to replace typical computers. In practice, they will be separate instruments used to solve complex, data-heavy problems, particularly those that make use of machine learning, where the system can make predictions and improve over time.
