The Robust QCA Adder Designs Using Composable QCA Building Blocks

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2007
Quantum-dot cellular automata (QCA) is attracting a lot of attention due to its extremely small feature size and ultralow power consumption. Up to now, several adder designs using QCA technology have been proposed. However, it was found that not all of the designs function properly.

Magnetic QCA systems

Microelectronics Journal, 2005
The field-coupled QCA architecture has emerged as a candidate for providing local interconnectivity for nanodevices, and offers the possibility to perform very dense, high speed, and low power computing in an altogether new paradigm. Magnetic interactions between nanomagnets are sufficiently strong to allow room-temperature operation.

Comparison of QCA systems

The International Journal of Cardiac Imaging, 1997
Excellent agreement between different 'second generation' systems for quantitative coronary arteriography (QCA) has been found in in vitro measurements. To verify the quality and stability of QCA when used in clinical practice, three QCA systems (AWOS, Cardio, and CMS) were used in a representative set of coronary artery lesions.This set consisted of ...

Testing QCA Modular Logic

2006 13th IEEE International Conference on Electronics, Circuits and Systems, 2006
we propose a design for testability of arbitrary combinational Quantum Dot Cellular Automata (QCA) logic, which facilitates its functionality testing. Any combinational logic can be implemented using only AND-OR gates (with negated signals available), and in QCA this results in reduced test set.

QCA Systolic Matrix Multiplier

2010 IEEE Computer Society Annual Symposium on VLSI, 2010
Quantum-dot Cellular Automata (QCA) technology is a promising alternative to CMOS technology. It is attractive due to its fast speed, small area and low power consumption. To explore the characteristics of QCA technology, digital circuit design approaches have been investigated.

Architecture and tools for programmable QCA

2011 International Conference on Field-Programmable Technology, 2011
Quantum-dot Cellular Automata (QCA) is a nano-scale compute fabric being explored by the VLSI research community as the difficulties in shrinking CMOS transistors mount. The paradigm promises high device densities and power-efficiency, and has unique properties that make it an interesting candidate for programmable devices.

Design of efficient QCA multiplexers

International Journal of Circuit Theory and Applications, 2015
SummaryA new methodology to realize efficient multiplexers using quantum‐dot cellular automata (QCA) is presented in this paper. The novel designs here demonstrated fully exploit the intrinsic logic capabilities of the basic building block in the QCA domain: the Majority Gate.
