Towards hybrid circuit quantum electrodynamics with quantum dots

Cavity quantum electrodynamics allows one to study the interaction between light and matter at the most elementary level. The methods developed in this field have taught us how to probe and manipulate individual quantum systems like atoms and superconducting quantum bits with an exquisite accuracy. There is now a strong effort to extend further these methods to other quantum systems, and in particular hybrid quantum dot circuits. This could turn out to be instrumental for a noninvasive study of quantum dot circuits and a realization of scalable spin quantum bit architectures. It could also provide an interesting platform for quantum simulation of simple fermion-boson condensed matter systems. In this short review, we discuss the experimental state of the art for hybrid circuit quantum electrodynamics with quantum dots, and we present a simple theoretical modeling of experiments.Comment: Minor differences with published versio

Powerscapes

Thesis (M. Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 2012.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (p. 149-151).In 2050, global oil supply will decline to 1/8 of today's. Migrating to the Post-Oil Era, over 10000's km2 of Powerscapes - the solar-collecting infrastructure - will be gradually constructed across the arid desert, for the indispensable production of solar energy to sustain Middle East's economy and global energy supply. The contingency of introducing the Powerscapes is a spatial problem. Unlike a powerplant that burns coal or oil, the scale of the Powerscapes is dramatically extensive. The inserted Powerscapes will interiorize the desert landscape and shelter the ground from the harsh direct sunlight that will be captured for power supply. Transformation in biological development, meteorological activity and geological phenomena will be inevitable, but the change that reduces the heat and evaporation rate will make its climatatic dynamics more habitable for human, animals and plants - an invaluable opportunity for the synthesis of energy production and climate conditioning. This thesis investigates the strategic programming and spatial configuration of such constructed landscape, capitalized by its new temporal characteristics, and sensitively adapting to it. Layers of material will be organized to form "Strata" of temporal conditions to be stretched across the landscape. To forge a symbiotic relationship between Solar Collection, human habitation, agricultural production and wild nature, the layers of material will delineate, push, flip, intersect, puncuate, wrap and merge, responding to programmatic needs and geographical dynamics that the natural geology and the Powerscapes together create. Such adaptive organization also permits certain geometrical and configuration logic to reiterate themselves in multiple scales, formulating a fractalic field with recursive part to whole relationships.by Chun Lun Otto Ng.M.Arch
