Molecular Magnetic Quantum Cellular

This report examines a specific nanoscale computing technology, namely Magnetic Quantum Cellular Automata (MQCA) systems. It provides estimates of the temperature stability and operating speed as a function of the device size, together with estimates of how such systems might behave if the device sizes could be scaled down to molecular dimensions.
