The goal of the program was to develop atom + cavity QED systems capable of storing and coherently manipulating quantum information coded in long-lived ground states of trapped atoms. We have developed atom traps designed to trap arrays of atoms inside high-finesse optical resonators. We have incorporated these atom traps into our high-finesse optical resonators and distilled the number of atoms in the traps down to the single atom level. Our implementation will enable coherent quantum information processing between atomic qubits readily scalable to>20 qubits. The theoretical effort of this program focused on two goals: (1) exploring alternative strategies for atomic and optical-based systems capable of storing and manipulating quantum information, and (2) supporting the experimental program by providing detailed study of the laboratory systems.

(cont.) Cavity cooling is demonstrated for the first time with trapped ions, and for the first time in the parameter regime where cooling to the motional ground state is possible. The measured cavity cooling dynamics are found to agree with a rate equation model without any free parameters. The third and final part of the thesis presents a theoretical proposal for interconversion between single trapped ion qubits and single photon qubits for quantum communication. The idea is to map the state of the single ion qubit to a superradiant collective state of several ions, which then couples strongly with single photons in an optical cavity.

Complex systems are systems that comprise many interacting parts with the ability to generate a new quality of collective behavior through self-organization, e.g. the spontaneous formation of temporal, spatial or functional structures. These systems are often characterized by extreme sensitivity to initial conditions as well as emergent behavior that are not readily predictable or even completely deterministic. The recognition that the collective behavior of the whole system cannot be simply inferred from an understanding of the behavior of the individual components has led to the development of numerous sophisticated new computational and modeling tools with applications to a wide range of scientific, engineering, and societal phenomena. Computational Complexity: Theory, Techniques and Applications presents a detailed and integrated view of the theoretical basis, computational methods, and state-of-the-art approaches to investigating and modeling of inherently difficult problems whose solution requires extensive resources approaching the practical limits of present-day computer systems. This comprehensive and authoritative reference examines key components of computational complexity, including cellular automata, graph theory, data mining, granular computing, soft computing, wavelets, and more.

With continued development of laser-atom interaction, systems of trapped ions offer a promising platform for the realization of fault-tolerant quantum information processing (QIP). Much progress with single atomic and molecular ion qubits has been made both in theory and experiment on the fundamental building blocks for scalable QIP architectures. Nonetheless, difficulty still remains for quantum network implementation and spectroscopy protocols for atomic and molecular ions, respectively. The objective of this thesis is to design and test the ion trap integration with photon resonators, which can facilitate coherent ion-photon state transfer in quantum networks, and microwave spectroscopy for molecular ion rotational states. The first part of the thesis describes a novel planar trap design with an integrated optical cavity. Proposals for photon number memory with trapped ions are presented, and experimental implementation for single ion cavity QED is explored. In addition, a study of vacuum-induced scattering loss increase is performed for mirror coatings at several temperatures and wavelengths, from which a method of retaining cavity finesse was developed. In the second part, an experiment is proposed for microwave quantum logic spectroscopy of molecular ions. With a cavity field to facilitate entanglement between co-trapped single atomic and molecular ions, a reliable and non-destructive spectroscopy method, as well as molecular ground state cooling can be realized.

Quantum processing and communication is emerging as a challenging technique at the beginning of the new millennium. This is an up-to-date insight into the current research of quantum superposition, entanglement, and the quantum measurement process - the key ingredients of quantum information processing. The authors further address quantum protocols and algorithms. Complementary to similar programmes in other countries and at the European level, the German Research Foundation (DFG) realized a focused research program on quantum information. The contributions - written by leading experts - bring together the latest results in quantum information as well as addressing all the relevant questions.

The field of atomic, molecular, and optical (AMO) science underpins many technologies and continues to progress at an exciting pace for both scientific discoveries and technological innovations. AMO physics studies the fundamental building blocks of functioning matter to help advance the understanding of the universe. It is a foundational discipline within the physical sciences, relating to atoms and their constituents, to molecules, and to light at the quantum level. AMO physics combines fundamental research with practical application, coupling fundamental scientific discovery to rapidly evolving technological advances, innovation and commercialization. Due to the wide-reaching intellectual, societal, and economical impact of AMO, it is important to review recent advances and future opportunities in AMO physics. Manipulating Quantum Systems: An Assessment of Atomic, Molecular, and Optical Physics in the United States assesses opportunities in AMO science and technology over the coming decade. Key topics in this report include tools made of light; emerging phenomena from few- to many-body systems; the foundations of quantum information science and technologies; quantum dynamics in the time and frequency domains; precision and the nature of the universe, and the broader impact of AMO science.

The development of scalable microfabricated ion traps with multiple segments for the realization of quantum computing is a challenging task in quantum information science. The research on the design, development, fabrication, and operation of the first European micro-trap is shown in this thesis. This chip-based micro-trap is an outstanding candidate towards experiments for a future quantum processor with trapped single ions. In the experiments coherent quantum state manipulation is demonstrated, and sideband cooling to the motional ground state is realized. The heating rate is determined and the applicability for quantum computation is proven. Furthermore planar trap designs are investigated - a planar microparticle trap was built and operated. A linear microfabricated planar trap was operated, showing the proof of concept of a novel designed and fabricated Y-shaped planar trap.

Practical quantum computing still seems more than a decade away, and researchers have not even identified what the best physical implementation of a quantum bit will be. There is a real need in the scientific literature for a dialogue on the topic of lessons learned and looming roadblocks. This reprint from Quantum Information Processing is dedicated to the experimental aspects of quantum computing and includes articles that 1) highlight the lessons learned over the last 10 years, and 2) outline the challenges over the next 10 years. The special issue includes a series of invited articles that discuss the most promising physical implementations of quantum computing. The invited articles were to draw grand conclusions about the past and speculate about the future, not just report results from the present.
