Efficient and Robust Delay-Insensitive QCA (Quantum-Dot Cellular Automata) Design

2006 21st IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems, 2006
The concept of clocking for QCA, referred to as the four-phase clocking, is widely used. However, inherited characteristics of QCA, such as the way to hold state, the way to synchronize data flows, and the way to power QCA cells, make the design of QCA circuits quite different from VLSI and introduce a variety of new design challenges.

A novel universal (FNZ) gate in quantum dot cellular automata (QCA)

IMPACT-2013, 2013
As transistor geometries are reduced, quantum effects begin to dominate device performance. At some point, transistors cease to have the properties that make them useful computational components. New computing elements must be developed in order to keep pace with Moore's Law.

Power gain in a quantum-dot cellular automata (QCA) shift register

Proceedings of the 2001 1st IEEE Conference on Nanotechnology. IEEE-NANO 2001 (Cat. No.01EX516), 2002
Discusses an experiment that demonstrates power gain in a quantum-dot cellular automata (QCA) shift register. Power gain is essential in any electronic system for the restoration of logic levels. The clock signal plays an important role in providing power gain in QCA devices as it can be used as a source of energy for the system.

Fault modeling and mapping for quantum-dot cellular automata (QCA) designs

2013 2nd International Conference on Advances in Electrical Engineering (ICAEE), 2013
This paper addresses the issue of fault modeling and mapping between a design done at the CMOS gate-level and one done using QCA technology. Since QCA and CMOS gate-level defects differ completely, it is important to investigate the mapping between classical single stuck-at fault (SSF) modeling and QCA defect and failure modes.

Molecular Quantum-dot Cellular Automata (QCA): Characterization of the bis-ferrocene molecule as a QCA device.

2013
Quantum-dot cellular automata is an emerging technology for digital computation that follows the More than Moore trends and aims to the simultaneous reduction of both device size and power consumption. In particular, the basic QCA device is a cell made of dots and in which a bunch of free charges are allowed to move without leaving the cell itself ...
