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 ...

Targeted tumour theranostics in mice via carbon quantum dots structurally mimicking large amino acids

Nature Biomedical Engineering, 2020
Strategies for selectively imaging and delivering drugs to tumours typically leverage differentially upregulated surface molecules on cancer cells. Here, we show that intravenously injected carbon quantum dots, functionalized with multiple paired α ...

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).

Graphene Quantum Dots

Particle & Particle Systems Characterization, 2013
Graphene quantum dots (GQDs) are nanometer‐sized fragments of graphene that show unique properties, which makes them interesting candidates for a whole range of new applications. This review article gives an overview of the synthesis, properties and applications of GQDs. Synthesis methods discussed include top‐down and bottom‐up approaches.
