Quantum walks in an array of quantum dots [PDF]

Journal of Physics A: Mathematical and Theoretical, 2008
Quantum random walks are shown to have non-intuitive dynamics, which makes them an attractive area of study for devising quantum algorithms for well-known classical problems as well as those arising in the field of quantum computing. In this work we propose a novel scheme for the physical implementation of a discrete-time quantum random walk using ...

Analysis of As/GaAs quantum dot solar cells using Suns-Voc measurements [PDF]

, 2014
The performance of InAs/GaAs quantum dot solar cells was investigated up to an optical concentration of 500-suns. A high temperature spacer layer between successive layers of quantum dots was used to reduce the degradation in the open circuit voltage ...

Quantum-dot devices and Quantum-dot Cellular Automata

Journal of the Franklin Institute, 1997
We discuss novel nanoelectronic architecture paradigms based on cells composed of coupled quantum-dots. Boolean logic functions may be implemented in specific arrays of cells representing binary information, the so-called Quantum-Dot Cellular Automata (QCA).
