Abstract :
Quantum cellular automata, also known as QCA, has been touted as a pragmatic use of quantum phenomena which currently are detrimental in nano-transistor technology. Recently, QCA technologies has expanded into magnetism, an area referred to as magnetic QCA, by exploiting the magnetic coupling interaction between neighboring cells (nano-magnets). The interactions of orderly fabricated nano-magnets and the viability of nano-magnetic structures as logical building blocks has yet to be explored in great detail. We have fabricated nano-scale magnetic QCA cells and currently the scope entails determining how factors such as material, size, placement, and surface roughness affect the magnetic properties and coupling interactions between the nano- magnetic QCA cells.
