This paper presents an overview of the electronic implementation of quantum-dot cellular automata (QCA). QCA is a computing paradigm that encodes and processes information by the position of individual electrons. This opens the possibility of dense, ultra-low power devices. Resent results are presented from QCA cells implemented using metal-dots, as well as investigations toward molecular and silicon QCA devices.
