Design and Simulation of Innovative QCA Quaternary Logic Gates
Advanced Theory and Simulations, 2021 AbstractThis paper proposes a new cell configuration for quaternary Quantum Cellular Automata (QQCA) based on the calculation of polarization. The proposed QQCA cell is based on a three‐particle system that creates instability within a cell in the gate design. Therefore, a single‐particle system or binary QCA (bQCA) technology and a two‐particle system

Design and analysis of area efficient QCA based reversible logic gates
Microprocessors and Microsystems, 2017 Abstract The CMOS technology has been plagued by several problems in past one decade. The ever increasing power dissipation is the major problem in CMOS circuits and systems. The reversible computing has potential to overcome this problem and reversible logic circuits serve as the backbone in quantum computing.

Priority encoder using reversible logic gates in QCA
2017 8th IEEE Annual Information Technology, Electronics and Mobile Communication Conference (IEMCON), 2017 Reversible logic gate has gained importance in recent times due to its low power dissipation and less information loss. QCA on the other hand has low power consumption and has applications in reversible logic. In this paper, a 4×2 priority encoder is proposed which is based on reversible logic implemented in QCA. Firstly, this paper discusses about QCA

Design of Testable Universal Logic Gate Targeting Minimum Wire-Crossings in QCA Logic Circuit
2010 53rd IEEE International Midwest Symposium on Circuits and Systems, 2010 Wire crossings limit the performance of a logic circuit in Quantum-Dot Cellular Automata (QCA) based design. Minimization of wire-crossings is, therefore, of prime importance in the current nanotechnology, susceptible to high error rates. This work proposes a QCA (Quantum-Dot Cellular Automata) logic gate (UQCALG) realizing the universal functions. The

Multifunction reversbile logic gate: Logic synthesis and design implementation in QCA
2017 International Conference on Computing, Communication and Automation (ICCCA), 2017 Quantum-dot Cellular Automata (QCA) is a newly developed paradigm for digital design. It explains how computation can be performed using nano sized quantum dots. One of the trending application of QCA is the design of reversible logic circuits and gates. Reversible logic is a dissipation less digital logic.

Design of universal logic gate targeting minimum wire-crossings in QCA logic circuit
2010 13th Euromicro Conference on Digital System Design: Architectures, Methods and Tools, 2010 This work proposes a testable QCA (Quantum-Dot Cellular Automata) logic gate (UQCALG) realizing the universal functions. The design of UQCALG is based on the Coupled Majority Minority (CMVMIN) QCA structure with the target to reduce wire crossings as well as the number of clock cycles required to operate a QCA circuit.
