An efficient design of full adder in quantum-dot cellular automata (QCA) technology
Microelectronics Journal, 2016The full adder circuit is a basic unit in digital arithmetic and logic circuits. In this paper an improved full adder in QCA technology is proposed. This design is considerably declined in terms of cell numbers and area, compared to other full adders and delay is kept at minimum.

Efficient Design of Vedic Square Calculator Using Quantum Dot Cellular Automata (QCA)
IEEE Transactions on Circuits and Systems II: Express Briefs, 2022Self-multiplier or square calculator design using the Vedic formulas is the new trend in quantum-dot cellular automata (QCA) technology. However, an efficient coplanar design and a complete performance analysis are still desired. This brief presents the coplanar QCA architecture of a 2-bits square calculator (proposed design-1 or PD1) using the Vedic ...

Efficient Simulation of Correlated Dynamics in Quantum-Dot Cellular Automata (QCA)
IEEE Nanotechnology Magazine, 2014Many simulations of quantum-dot cellular automata (QCA) rely upon the so-called intercellular Hartree approximation (ICHA), which neglects the possibility of entanglement between cells. While the ICHA is useful for solving many QCA circuits due to its relative simplicity and computational efficiency, its many shortcomings make it prohibitive in ...

Reversible computation with quantum-dot cellular automata (QCA)
Proceedings of the 2nd conference on Computing frontiers, 2005Quantum-dot cellular automata (QCA) is a strategy in which binary data is represented by charge configuration within a multi-dot cell. Data is transmitted to nearest neighbors by the Coulombic interaction. An electric field acts as a clock and imposes directionality on circuits. We have explored the connection between logical reversibility and physical

Quantum-Dot Cellular Automata (QCA) circuit partitioning
Proceedings of the 41st annual Design Automation Conference, 2004This paper presents the Quantum-Dot Cellular Automata (QCA) physical design problem, in the context of the VLSI physical design problem. The problem is divided into three subproblems: partitioning, placement, and routing of QCA circuits. This paper presents an ILP formulation and heuristic solution to the partitioning problem, and compares the two sets
