Design and implementation of digital circuits using Quantum Dot Cellular Automata (QCA)

DEEPAK SOURAV R, K. B RAMESH

Abstract


This paper explores Quantum Dot Cellular Automata (QCA) as a potential replacement for current chip technologies. It discusses how QCA is better in terms of size, power, and timing. Starting with basic gate studies, it moves on to designing different parts of a computer chip. The paper shows ongoing work through computer simulations, highlighting how QCA is both efficient and small, like in a special kind of flip-flop. They also introduce a new kind of logic circuit called Majority Gate, which performs well than what we use now. The study ends by showing how QCA can be used for quantum computing, giving an example of a chip design that handles tricky situations well.
