Abstract :
Discusses an experiment that demonstrates power gain in a quantum-dot cellular automata (QCA) shift register. Power gain is essential in any electronic system for the restoration of logic levels. The clock signal plays an important role in providing power gain in QCA devices as it can be used as a source of energy for the system. We discuss how this can be achieved in a QCA shift register and experimentally demonstrate a power gain greater than unity
