Sie hat alles gehabt und alles verloren: Sekunden der Unachtsamkeit kosten ihre einzige Tochter das Leben. Tief sieht Linda in den Abgrund und ware beinahe gefallen, doch da sind hauchfeine Faden, die sie halten die Hundin Kaja, die steten Handgriffe im Garten, das Mitgefuhl fur andere. Wie viel Kraft in ihr steckt, ahnt sie erst, als sie zuruckfindet in einen Alltag und zu sich selbst.

This thesis sheds new light on the fascinating properties of composite quantum systems.Quantum systems of different sizes, ranging from small bipartite systems to large many-body ensembles, can be studied with the help of modern quantum optical experiments. These experiments make it possible to observe a broad variety of striking features, including nonclassical correlations, complex dynamics and quantum phase transitions. By adopting the complementary perspectives of quantum information theory, quantum chemistry and many-body theory, the thesis develops new methods for the efficient characterization and description of interacting, composite quantum systems.

Sensors are effective tools used to carry out cost-effective, fast, and reliable sensing for a wide range of applications. This volume presents a brief history behind sensing technology and highlights a broad range of biosensing techniques based on optical and electrochemical response methods. Starting from the traditional enzyme-based biosensing method to functionalized nanostructure-based sensors, this book also provides a detailed overview of some of the advanced sensing methodologies based on photonic crystal cavity-based sensing devices.

This book presents theoretical methods and experimental results on the study of multipartite quantum correlations in spin-squeezed BoseEinstein condensates. Nonclassical correlations in many-body systems are particularly interesting for both fundamental research and practical applications. For their investigation, ultracold atomic ensembles offer an ideal platform, due to their high controllability and long coherence times. In particular, we introduce criteria for detecting and characterizing multipartite entanglement, EinsteinPodolskyRosen steering, and Bell correlations. Moreover, we present the experimental observation of such correlations in systems of about 600 atoms.

Hay algunos conceptos de la realidad que debemos de mejorar. Seguimos considerando a la luz separada de la materia como la separó Dios en el día primero. La materia produce y absorbe la luz. No podemos separarlas. Cualquier particula se transforma en luz si se encuentra con su antiparticula. Podemos digitalizar el universo contando sus fotones. Digitalizamos la realidad y nos podemos trasladar por el espacio en forma de luz. Mantenemos todavia los conceptos de espacio y tiempo absolutos que descubrio Newton hace ya casi cuatro siglos. Cada dia inventamos vehiculos mas rapidos y seguimos aceptando que no podemos superar la velocidad de la luz que fijo Einstein. Puede que si y que podamos trasladarnos por las estrellas. Seguro que hay energias nuevas que estan por descubrir y que no producen dioxido de carbono. El modelo de vacio, atomo y tabla periodica seguro que estan desfasados. Que decir de la sintesis, lo hemos comprobado con las vacunas y las quimioterapias… Que decir del universo y de la vida. La mayoria de las zonas del espectro electromagnetico estan por experimentar. Gracias.

Superconducting quantum circuits are among the most promising solutions for the development of scalable quantum computers. Built with sizes that range from microns to tens of metres using superconducting fabrication techniques and microwave technology, superconducting circuits demonstrate distinctive quantum properties such as superposition and entanglement at cryogenic temperatures. This book provides a comprehensive and self-contained introduction to the world of superconducting quantum circuits, and how they are used in current quantum technology. Beginning with a description of their basic superconducting properties, the author then explores their use in quantum systems, showing how they can emulate individual photons and atoms, and ultimately behave as qubits within highly connected quantum systems. Particular attention is paid to cutting-edge applications of these superconducting circuits in quantum computing and quantum simulation. Written for graduate students and junior researchers, this accessible text includes numerous homework problems and worked examples.

A principios del siglo XX, dos teorías físicas sacudieron los cimientos del conocimiento humano. La relatividad de Einstein revolucionó nuestra comprensión del espacio, el tiempo y la materia. La mecanica cuantica, ideada por Planck, expulso el determinismo de las ecuaciones que rigen el microcosmos. La union de ambas teorias es, seguramente, el mayor desafio de la fisica teorica, el que permite la desaparicion de los conceptos de espacio y tiempo. La revolucion en la comprension del universo.

A re-issued edition of this well-known modern quantum mechanics textbook.

Quantum phenomena of many-particle systems are fascinating in their complexity and are consequently not fully understood and largely untapped in terms of practical applications. Ultracold gases provide a unique platform to build up model systems of quantum many-body physics with highly controlled microscopic constituents. In this way, many-body quantum phenomena can be investigated with an unprecedented level of precision, and control and models that cannot be solved with present day computers may be studied using ultracold gases as a quantum simulator. ,This book addresses the need for a comprehensive description of the most important advanced experimental methods and techniques that have been developed along with the theoretical framework in a clear and applicable format. The focus is on methods that are especially crucial in probing and understanding the many-body nature of the quantum phenomena in ultracold gases and most topics are covered both from a theoretical and experimental viewpoint, with interrelated chapters written by experts from both sides of research.Graduate students and post-doctoral researches working on ultracold gases will benefit from this book, as well as researchers from other fields who wish to gain an overview of the recent fascinating developments in this very dynamically evolving field. Sufficient level of both detailed high level research and a pedagogical approach is maintained throughout the book so as to be of value to those entering the field as well as advanced researchers. Furthermore, both experimentalists and theorists will benefit from the book, close collaboration between the two are continuously driving the field to a very high level and will be strengthened to continue the important progress yet to be made in the field._,
