Abstract :
This work targets design of reversible ALU (arithmetic logic unit) in QCA (Quantum-dot Cellular Automata) framework. The design is based on the reversible QCA structure (RQCA) introduced in this paper. A fault tolerant architecture of reversible ALU is also synthesized. The proposed designs are verified and evaluated over the existing ALU designs and found to be more efficient in terms of design complexity and quantum cost.
