Circuit Design With Quantum Cellular Automata

The quantum cellular automata (QCA) concept uses a rectangular cell with a bistable charge configuration to represent information. We first study QCA and its fundamental building blocks in detail. We then proceed to understand logic design using QCA gates. Next, we explore testing of QCA gates. We briefly discuss current computer-aided design (CAD) tools available for QCA design. Finally, we discuss the current state of QCA fabrication technology and briefly comment on future research directions.
