Abstract—The construct of computing is the field of ever improving and advancing systems and architectures. One of the emerging archetype that has made its ground as a research area is the concept of reversible logic in computing. Reversible logic suggests the systems with zero heat dissipation since the computational models in this logic incorporate the concept of reversibility at a ground lev...

Design of parity preserving logic based on emerging nanotechnology is very limited due to present technological limitation in tackling its high error rate. In this work, Quantum-dot cellular automata (QCA), a potential alternative to CMOS, is investigated for designing easily testable logic circuit.

In the molecular quantum-dot cellular automata (QCA) paradigm clocking wires are used to produce an electric field which is perpendicular to the device plane of surface-bound molecules and is sinusoidally modulated in space and time. This clocking field guides the data flow through the molecular QCA array. Power is dissipated in clocking wires due to the non-zero resistance of the conductors. W...

Quantum-dot cellular automata (QCA) is a paradigm for connecting nanoscale bistable devices to accomplish general-purpose computation. The idea has its origins in the technology of quantum dots, Coulomb blockade, and Landauer’s observations on digital devices and energy dissipation. We examine the early development of this paradigm and its various implementations.
