Design of an Efficient N × N Butterfly Switching Network in Quantum-Dot Cellular Automata (QCA)

Quantum-dot cellular automata (QCA) is a rapidly growing nanotechnology very well suited for designing ultra-dense, low-power, and high-performance digital circuits. In parallel computing, the multistage interconnection network (MIN) provides maximum bandwidth to the components and minimum latency access to the memory modules. Much research has been conducted on CMOS-based MINs for parallel comput...
