Abstract
Quantum-dot Cellular Automata (QCA) appeared as a comprehensive solution to the shortfalls CMOS technology is facing in case of nanoscale implementations. This emerging nanotechnological paradigm promises high speed, energy efficient computing. In this present scope, the concept of binary semaphore has been implemented using J-K Flipflop with the 4-dot 2-electron variant of Quantum-dot Cellular Automata. Later we analyze the proposed layout with respect to suitable well established metrics. In addition we provide a case study of the proposed semaphore layout on traffic control system which comes out to offer a way more optimized in respect of power utilization.
