Quantum computing has attracted considerable interest in the past decade as a possible way to deal with certain intractable problems of conventional digital computing. Quantum computers built using the versatile methods of solid-state technology are attractive because the many thousands of devices needed for such a computer could be fabricated with well-established technologies. However, the imperfections of solid-state devices constructed in laboratories and factories will limit the use of solid-state devices in quantum computing. The challenge for solid-state quantum computing is to find a. way to use devices without precise knowledge of their physical characteristics.

The current universe of computer applications is based on the technology of solid-state switching, which are correlated with solid state transistors and other electronic elements, developed from the principles of quantum physics postulated in the first quarter of the last century. Such technology is now approaching a level of saturation that leads to predicting stagnation of the application of computer systems in a future not too distant, if a new computer application technology will not replace it. In this context, another technology, also based on quantum physics has emerged as a solution, not only to the problem of the expected limitation of current technology but, more importantly, as a giant leap in the application possibilities: The Quantum Computation. This work aims to study the history of the development of quantum computing machines and its principles of functionality, positioning the state of the art technology and analyzing the prospects for its future application.
