Reversible computation with quantum-dot cellular automata (QCA)

Proceedings of the 2nd conference on Computing frontiers, 2005
Quantum-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

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.

Scalability of Globally Asynchronous QCA (Quantum-Dot Cellular Automata) Adder Design

Journal of Electronic Testing, 2008
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.
