Digital QCA Systems

The design of QCA Systems gives in depth knowledge about Nanodevice design through Quantum cellular automata technology to accomplish present binary system. The technology called QCA ( Quantum cellular automata Technology). While there is still much work to be done early experimental results indicate that QCA may be an extremely viable alternative to CMOS. QCA cells and a simple QCA logical device have been successfully fabricated and tested. However the actual design of many of the circuits and devices required for a QCA microprocessor have not yet even been considered. What is required is a methodology for constructing and designing QCA circuits that are essential for a design such as a microprocessor. Furthermore understanding how microprocessor components should be built/designed should assist in the design of QCA physical devices. In short what is required is a reference QCA architecture and the design tools to manipulate and analyze it. In an effort to successfully develop a viable understandable and usable QCA archi- tecture and digital design.
