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...

Quantum dot Cellular Automata (QCA) is one of the important nano-level technologies for implementation of both combinational and sequential systems. QCA have the potential to achieve low power dissipation and operate high speed at THZ frequencies. However large probability of occurrence fabrication defects in QCA, is a fundamental challenge to use this emerging technology. Because of these vari...

<span lang="EN-US">The high-performance digital circuits can be constructed at high operating frequency, reduced power dissipation, portability, and large density. Using conventional complementary-metal-oxide-semiconductor (CMOS) design process, it is quite difficult to achieve ultra-high-speed due scaling problems. Recently quantum dot cellular automata (QCA) are prosed develop logic ato...

Computer–added design of single-electron nanoelectronic circuits on quantum majority components has been implemented. Proposed methods building logic-arithmetic computing devices the combinational type, which implement an almost complete system logical functions in both and Boolean bases. Quantum cellular automata is a technology that emerged two decades ago, values states correspond to positio...
