Characterization, test, and logic synthesis of and-or-inverter (AOI) gate design for QCA implementation

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2005
Quantum-dot cellular automata (QCA) offers a new computing paradigm for nanotechnology. The basic logic elements of this technology are the majority voter (MV) and the inverter (INV). However, an experimental evaluation has shown that MV is not efficiently used during technology mapping by existing logic-synthesis tools.

Design of Testable 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.

Implementation of Ex-OR gate using QCA with NNI logic

2017 International Conference on Wireless Communications, Signal Processing and Networking (WiSPNET), 2017
Quantum Dot Cellular Automata (QCA) is an intriguing transistor-less technology which can be rendered to switch from the existing CMOS technology. The basic logic state in QCA is determined by the polarity of electrons in a QCA cell rather than voltage level provided by the source. Basically, QCA consists of a majority voter gate and an inverter.

A STUDY ON DIVERSE NANOSTRUCTURE FOR IMPLEMENTING LOGIC GATE DESIGN FOR QCA

International Journal of Nanoscience, 2011
Quantum dot cellular automata (QCA) define the nanostructure of basic computer. It is used as an alternative for designing high-speed computer over CMOS technology. The basic logic in QCA is the logic state that does not measure with voltage level; rather it measures the polarity of electrons in cell.
