Abstract
An overview is given of the quantum-dot cellular automata (QCA) architecture, along with a summary of experimental demonstrations of QCA devices. QCA is a transistorless computation paradigm that can provide a solution to such challenging issues as device and power density. The basic building blocks of the QCA architecture, such logic gates and clocked cells have been demonstrated. The experiments to date have used QCA cells composed of metallic islands, and operate only at low temperatures. For QCA to be practical, the operating temperature must be raised, and molecular implementations are being investigated that should yield room temperature operation.
