The project 'Multi-Photon Entanglement and Quantum Teleportation' concerns a series of experimental and theoretical investigations on multi-photon entangled states and the applications, for example, quantum teleportation. The objective of this re search is to probe the foundations of quantum theory of entanglement and its fundamental roles in quantum computing and quantum information processing. This research will definitely benefit many scientific and engineering discipline applications. This report is for the first year investigation of a long term basic research program. The efforts of the first year research are very important for the achievement of our long term goal. Based on the successful results of the first year research, a novel teleportation experiment which has the ability to provide a true '100% teleportation' shall be conducted in the second year.

This comprehensive textbook on the rapidly advancing field introduces readers to the fundamental concepts of information theory and quantum entanglement, taking into account the current state of research and development. It thus covers all current concepts in quantum computing, both theoretical and experimental, before moving on to the latest implementations of quantum computing and communication protocols. It contains problems and exercises and is therefore ideally suited for students and lecturers in physics and informatics, as well as experimental and theoretical physicists in academia and industry who work in the field of quantum information processing. The second edition incorporates important recent developments such as quantum metrology, quantum correlations beyond entanglement, and advances in quantum computing with solid state devices.

This thesis describes experimental generation, manipulation and measurement of quantum information using photon pairs emitted in bulk crystals. Multi-photon sources engineered during the course of this thesis have proven to be ideal for original contributions in the field of optical quantum information. In the first part of this dissertation, we study nonlocality, bound entanglement and measurement-based quantum computing using entangled resources produced by our source. First, we produced and characterised three-photon GHZ polarisation states. We then experimentally violate the long-standing Svetlichny's inequality with a value of 4.51, which is greater than the classical bound by 3.6 standard deviations. Our results agree with the predictions of quantum mechanics, rule out nonlocal hidden-variable theories and certify the genuine tripartite entanglement achievable by our source. Second, with four-photon polarisation states, we demonstrate bound entanglement in Smolin states and realize all of their conceptually important characteristics. Our results highlight the difficulties to achieve the critical condition of undistillability without completely losing entanglement. We conclude the first part by simulating, for the first time, valence-bond solid states and use them as a resource for measurement-based quantum computing. Affleck-Kennedy-Lieb-Tasaki states are produced with 87% fidelity and single-qubit quantum logic gates reach an average fidelity of 92% over all input states and rotations. In the second part of this dissertation, we explore controlled waveform manipulation at the single-photon level. Specifically, we shrink the spectral bandwidth of a single photon from 1740 GHz to 43 GHz and demonstrate tunability over a range 70 times that bandwidth. The results are a considerable addition to the field of quantum frequency conversion and have genuine potential for technological applications.

Unique in that it is jointly written by an experimentalist and a theorist, this monograph presents universal quantum computation based on quantum teleportation as an elementary subroutine and multi-party entanglement as a universal resource. Optical approaches to measurement-based quantum computation are also described, including schemes for quantum error correction, with most of the experiments carried out by the authors themselves. Ranging from the theoretical background to the details of the experimental realization, the book describes results and advances in the field, backed by numerous illustrations of the authors' experimental setups. Aimed at researchers, physicists, and graduate and PhD students in physics, theoretical quantum optics, quantum mechanics, and quantum information.

The nonlocal correlations of entangled systems are a feature inherent to quantum theory that is fundamentally at odds with our common-sense notions of realism and locality. Additionally, entanglement is an essential resource for numerous quantum communication protocols such as quantum teleportation and quantum dense coding, quantum cryptography, as well as quantum-enhanced metrological schemes and quantum computation. These quantum schemes allow for significant gains in performance over their classical counterparts, and a commercial implementation of protocols utilizing entangled photons thus seems likely in the foreseeable future. A key challenge to be addressed, in order to achieve a global-scale implementation of quantum-enhanced protocols, is the distribution of entanglement over long distances. While photons are in many ways ideal carriers of quantum information, their distribution over long distances is significantly impeded by losses. At present, loss in optical fiber links or atmospheric attenuation and obstructions of the line of sight in terrestrial free-space links limit the distribution of photonic entanglement to several hundred kilometers. Installing sources of photons with quantum correlations on space platforms would allow such distance limitations to be overcome. This would not only lead to the first global-scale implementation of quantum communication protocols, but would also create the opportunity for a completely new class of quantum experiments in a general relativistic framework. State-of-the-art laboratory sources of entangled photons are generally ill-suited for applications in harsh environments such as space, either owing to the use of bulky lasers, the requirement for active interferometric stabilization, or insufficient photon-pair-generation efficiency. Thus, an integral milestone for the experimental implementation of quantum communication protocols over satellite links is the development of robust, space-proof sources of entangled photons with high brightness and entanglement visibility. This thesis is intended to bridge laboratory experiments and real-world applications of quantum entanglement in harsh operational conditions. To this end, the main results of this thesis are: Highly efficient sources of polarization-entangled photons for the distribution of entanglement via long-distance free-space links. The sources are very robust and compact, and incorporate only components which are compliant with the severe requirements of space flight and operation. Optimization of spectral properties and fiber-coupling efficiency of photon pairs generated via spontaneous parametric down-conversion in bulk periodically poled potassium titanyl phosphate. The results of these studies are of great practical relevance for the development of an ultra-stable and efficient entangled photon source. Engineering and characterization of field-deployable polarization-entangled photon sources with high visibility (>99%) and record pair-detection rates (>3 million detected pairs per mW of pump power). As a result of the performance demonstrated, the sources developed have been incorporated into ongoing experiments, for example in quantum nanophotonics and quantum communications, and will provide an enabling tool for future real-world applications.

Photons are an attractive option for testing fundamental quantum physics and developing new quantum-enhanced technology, including highly advanced computers and simulators, as well as precision sensing beyond shot-noise. Traditionally, bulk optical components have been bolted onto optical benches to realize metre-scale quantum circuits. However this approach is ultimately proving unwieldy for increasing the complexity and for scaling up to practical quantum technologies based on photons. The work presented here demonstrates a series of quantum photonic devices based on waveguide circuits embedded in miniature monolithic chips. This represents a paradigm shift in the underlying architecture of quantum optics and provides key building blocks for all-optical and hybrid quantum technologies.
