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...

Quantum-dot cellular automata ~QCA! may offer a viable alternative of traditional transistor-based technology at the nanoscale. When modeling a QCA circuit, the number of degrees of freedom necessary to describe the quantum mechanical state increases exponentially making modeling even modest size cell arrays difficult. The intercellular Hartree approximation largely reduces the number of state ...

Power dissipation is the main limitation of all the nano electronics design techniques including Quantumdot Cellular Automata (QCA). The reversible computing is considered as the reliable solution to lower the power dissipation. In this paper, the contribution is divided into three parts. In the first part, a multi-objective synthesis method is presented for reversible functions (with the objec...

Quantum cellular automata (QCA) enables performing arithmetic and logic operations at the molecular scale. This nanotechnology promises high device density, low power consumption and high computational power. Unlike the CMOS technology where the ON and OFF states of the transistors represent binary information, in QCA, data is represented by the charge configuration. The primary and basic devic...

A nano-scale quantum-dot cellular automaton (QCA) is one of the most promising replacements for CMOS technology. Despite potential advantages this technology, QCA circuits are frequently plagued by numerous forms manufacturing faults (such as a missing cell, extra displacement and rotated cell), making them prone to failure.
