Majority Gate Based Design for Combinational Quantum Cellular Automata (QCA) Circuits
Suresh Rai · Proceedings · 2008
Quantum cellular automata (QCA) present an important nanotechnology paradigm to design digital logic. A cell consists of four quantum dots located at the corners of a square. This paper considers the design of complex logic blocks using a fundamental QCA device, which is a three input majority logic gate. Our technique uses the 'disjointing concept', commonly used in the reliability literature. Our comparison with two existing approaches shows that the proposed method provides an efficient solution.
