Several new metallic and semiconducting nanostructures may provide interesting substrates for observations involving quantum coherence. Boron-based nanotubes with beryllium atoms in the hexagonal faces should exhibit uniformly metallic properties with multiple conduction channels of disparate character. The apical dislocation in a carbon nanocone mixes

Optical quantum gates with semiconductor nanostructures
International Journal of Circuit Theory and Applications, 2001An all optical implementation of quantum information processing with semiconductor macroatoms is presented. Our quantum hardware consists of an array of semiconductor quantum dots and the computational degrees of freedom, i.e. the qubits, are energy-selected interband optical transitions.

Fabrication of quantum dot and cavity nanostructures
2015 17th International Conference on Transparent Optical Networks (ICTON), 2015In this tutorial, I'll discuss fabrication aspects of cavities that contain quantum dots as active emitters. As far as the quantum dots are concerned, the most established fabrication technique is self-assembled Stranski-Krastanov growth [1]. This mechanism relies on the supply of a material with a lattice constant larger than that of the substrate ...

Efficient modelling of quantum nanostructures
Numerical Simulation of Optoelectronic Devices, 2014, 2014Calculation of the higher order modes for the Time Dependent Schrodinger's equation (TDSE). The Imaginary Time Propagation (ITP) method is used to solve the TDSE where this reduces the computational effort required to solve the TDSE. Also using the adjoint variable method the energy level sensitivity for higher order modes has been calculated for the ...

Nanostructures: Superlattices, Quantum Wires, and Quantum Dots
2014The advanced microfabrication techniques can produce objects which are sufficiently small, that new quantum effects appear. After discussing superlattices and Bloch oscillations, we turn to the Landauer transmission channels and the quantized conductance of quantum wires.

Quantum Optomechanics with Silicon Nanostructures
2013Mechanical resonators are the most basic and ubiquitous physical systems known. In on-chip form, they are used to process high frequency signals in every cell phone, television, and laptop. They have also been in the last few decades in different shapes and forms, a critical part of progress in quantum information sciences with kilogram-scale mirrors ...
