Nanotechnology, quantum information theory and quantum computing

Significant progress has been made in various applications of nanotechnology, and much efforts have been concentrated on the theory of nanocomputers. There are the need to examine nanocomputer architectures which include the following major components: the arithmetic-logic unit, the memory unit, the input/output unit, and the control unit. The recent results illustrate that novel logic and memory nanoscale integrated circuits can be fabricated and implemented. This progress is primarily due to the application of nanotechnology. Fundamental and applied results researched in this paper further expand the horizon of nanocomputer theory and nanotechnology practice. It is illustrated that novel nanocomputer architectures and organizations must be discovered and examined to ensure the highest level of efficiency, flexibility and robustness.
