Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse porte sur la recherche et l’étude de nouveaux moyens de coder et manipuler de l’information sur des systèmes quantiques. On peut, sur ceux-ci, continuer d’utiliser la logique usuelle (classique) afin de gagner en taille et en rapidité, ou développer une nouvelle logique (quantique) utilisant les propriétés quantiques de ces systèmes afin de faire des opérations irréalisables en logique classique. Les supports de l’information retenus ici sont des états propres de molécules. Pour pouvoir y manipuler l’information, il faut en contrôler la dynamique, ici par l’emploi d’un champ laser mis en forme pour faire sur la molécule une transformation précise (impulsions TT ou STIRAP optimisées par algorithmes génétiques, ou calculées par contrôle optimal). L’objectif de ce travail était de rechercher des systèmes quantiques candidats parmi les molécules pour le calcul classique et quantique, et d’y simuler des portes logiques, avec des encodages de l’information et des méthodes de contrôle variées. Pour le calcul classique, l’implémentation d’un additionneur au moyen de processus STIRAP sur le dioxyde de soufre a été simulée, proposant ainsi une mise en œuvre pour l’implémentation d’une porte classique sur un système moléculaire quantique. Pour le calcul quantique, des circuits ont été implémentés par computation vibrationnelle sur le chlorure de bromoacétyl nitreux, l’acide nitreux et le thiosphogène contrôlés par contrôle optimal, confirmant le potentiel présenté par les molécules polyatomiques pour le calcul quantique. L’utilisation d’un réseau de molécules diatomiques ultra-froides piégées couplée par interaction dipolaire, comme support logique a également été étudiée.
Book Synopsis Dynamique et contrôle de systèmes quantiques ouverts by : Aurélie Chenel
Download or read book Dynamique et contrôle de systèmes quantiques ouverts written by Aurélie Chenel and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'étude des effets quantiques, comme les cohérences quantiques, et leur exploitation en contrôle par impulsion laser constituent encore un défi numérique pour les systèmes de grande taille. Pour réduire la dimensionnalité du problème, la dynamique dissipative se focalise sur un sous-espace quantique dénommé 'système', qui inclut les degrés de liberté les plus importants. Le système est couplé à un bain thermique d'oscillateurs harmoniques. L'outil essentiel de la dynamique dissipative est la densité spectrale du bain, qui contient toutes les informations sur le bain et sur l'interaction entre le système et le bain. Plusieurs stratégies complémentaires existent. Nous adoptons une équation maîtresse quantique non-markovienne pour décrire l'évolution de la matrice densité associée au système. Cette approche, développée par C. Meier et D.J. Tannor, est perturbative en fonction du couplage entre le système et le bain, mais pas en fonction de l'interaction avec un champ laser. Le but est de confronter cette méthodologie à des systèmes réalistes calibrés par des calculs de structure électronique ab initio. Une première étude porte sur la modélisation du transfert d'électron ultrarapide à une hétérojonction oligothiophène-fullerène, présente dans des cellules photovoltaïques organiques. La description du problème en fonction d'une coordonnée brownienne permet de contourner la limitation du régime perturbatif. Le transfert de charge est plus rapide mais moins complet lorsque la distance R entre les fragments oligothiophène et fullerène augmente. La méthode de dynamique quantique décrite ci-dessus est ensuite combinée à la Théorie du Contrôle Optimal (OCT), et appliquée au contrôle d'une isomérisation, le réarrangement de Cope, dans le contexte des réactions de Diels-Alder. La prise en compte de la dissipation dès l'étape d'optimisation du champ permet à l'algorithme de contrôle de contrer la décohérence induite par l'environnement et conduit à un meilleur rendement. La comparaison de modèles à une et deux dimensions montre que le contrôle trouve un mécanisme adapté au modèle utilisé. En deux dimensions, il agit activement sur les deux coordonnées du modèle. En une dimension, le décohérence est minimisée par une accélération du passage par les états délocalisés situés au-dessus de la barrière de potentiel.

Book Synopsis Strong Light-matter Coupling by : Leong Chuan Kwek
Download or read book Strong Light-matter Coupling written by Leong Chuan Kwek and published by World Scientific. This book was released on 2013-12-23 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physics of strong light-matter coupling has been addressed in different scientific communities over the last three decades. Since the early eighties, atoms coupled to optical and microwave cavities have led to pioneering demonstrations of cavity quantum electrodynamics, Gedanken experiments, and building blocks for quantum information processing, for which the Nobel Prize in Physics was awarded in 2012. In the framework of semiconducting devices, strong coupling has allowed investigations into the physics of Bose gases in solid-state environments, and the latter holds promise for exploiting light-matter interaction at the single-photon level in scalable architectures. More recently, impressive developments in the so-called superconducting circuit QED have opened another fundamental playground to revisit cavity quantum electrodynamics for practical and fundamental purposes. This book aims at developing the necessary interface between these communities, by providing future researchers with a robust conceptual, theoretical and experimental basis on strong light-matter coupling, both in the classical and in the quantum regimes. In addition, the emphasis is on new forefront research topics currently developed around the physics of strong light-matter interaction in the atomic and solid-state scenarios.

Book excerpt: NEW YORK TIMES BESTSELLER • “A fascinating look at how consumers perceive logos, ads, commercials, brands, and products.”—Time How much do we know about why we buy? What truly influences our decisions in today’s message-cluttered world? In Buyology, Martin Lindstrom presents the astonishing findings from his groundbreaking three-year, seven-million-dollar neuromarketing study—a cutting-edge experiment that peered inside the brains of 2,000 volunteers from all around the world as they encountered various ads, logos, commercials, brands, and products. His startling results shatter much of what we have long believed about what captures our interest—and drives us to buy. Among the questions he explores: • Does sex actually sell? • Does subliminal advertising still surround us? • Can “cool” brands trigger our mating instincts? • Can our other senses—smell, touch, and sound—be aroused when we see a product? Buyology is a fascinating and shocking journey into the mind of today's consumer that will captivate anyone who's been seduced—or turned off—by marketers' relentless attempts to win our loyalty, our money, and our minds.

Book Synopsis Strategic Management of Innovation and Design by : Pascal Le Masson
Download or read book Strategic Management of Innovation and Design written by Pascal Le Masson and published by Cambridge University Press. This book was released on 2010-09-09 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is now widespread agreement that innovation holds the key to future economic and social prosperity in developed countries. Experts studying contemporary capitalism also agree that the battle against unemployment and relocations can only be won through innovation. But what kind of innovation is required and what is the best way to manage, steer and organize it? Grounded on experiences of innovative firms and based on recent design theories, this book argues that instead of relying on traditional R&D and project management techniques, the strategic management of innovation must be based on innovative design activities. It analyses and explains new management principles and techniques that deal with these activities, including innovation fields, lineages, C-K (Concept-Knowledge) diagrams and design spaces. The book is ideal for advanced courses in innovation management in industrial design schools, business schools, engineering schools, as well as managers looking to improve their practice.
