Download or read book Narrowband Single Photons for Light-Matter Interfaces written by Markus Rambach and published by Springer. This book was released on 2018-08-28 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a step-by-step guide on how to construct a narrowband single photon source for the integration with atom-based memory systems. It combines the necessary theoretical background with crucial experimental methods and characterisations to form a complete handbook for readers at all academic levels. The future implementation of large quantum networks will require the hybridisation of photonic qubits for communication with quantum memories in the context of information storage. Such an interface requires carefully tailored single photons to ensure compatibility with the chosen memory. The source itself is remarkable for a number of reasons, including being the spectrally narrowest and brightest source of its kind; in addition, it offers a novel technique for frequency stabilisation in an optical cavity, together with exceptional portability. Starting with a thorough analysis of the current literature, this book derives the essential parameters needed to design the source, describes its individual components in detail, and closes with the characterisation of a single photon source.

This book was released on 2014 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: One promising approach for future quantum networks is the combination of strings of trapped ions as quantum-information processors with entangled photon pairs produced by spontaneous parametric down conversion (SPDC) to establish quantum communication links between distant processing units. This work reports on experiments using a hybrid quantum-optics set-up, comprising two separate linear ion traps and a resonant SPDC photon-pair source. It demonstrates the controlled interaction of single entangled photon pairs with a single trapped 40Ca+ ion. Preparing the ion as polarization selective absorber in the main polarization bases allows for the reconstruction of the biphoton quantum state, manifesting the photon entanglement in the absorption process. Beyond that, the thesis documents the implementation of additional experimental tools enabling quantum state transfer experiments from photons to single ions. A dedicated narrowbandwidth laser system is set up, laser sequences are developed for state discrimination and state rotations of ion qubits, and for the creation and characterization of coherent superposition states, of particular importance for state-transfer schemes. Finally, detection efficiencies of single Raman photons emitted by an ion are characterized with a well controlled single-photon source, and absorption probabilities of single photons are determined with a calibrated laser beam, providing precise values to assess efficiencies for different transfer scenarios.

Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the novel research in quantum memory networking, especially quantum memories based on cold atomic ensembles. After discussing the frontiers of quantum networking research and building a DLCZ-type quantum memory with cold atomic ensemble, the author develops the ring cavity enhanced quantum memory and demonstrates a filter-free quantum memory, which significantly improves the photon-atom entanglement. The author then realizes for the first time the GHZ-type entanglement of three separate quantum memories, a building block of 2D quantum repeaters and quantum networks. The author also combines quantum memories and time-resolved measurements, and reports the first multiple interference of three single photons with different colors. The book is of good reference value for graduate students, researchers, and technical personnel in quantum information sciences.

This book was released on 2019-04-27 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum mechanics, the subfield of physics that describes the behavior of very small (quantum) particles, provides the basis for a new paradigm of computing. First proposed in the 1980s as a way to improve computational modeling of quantum systems, the field of quantum computing has recently garnered significant attention due to progress in building small-scale devices. However, significant technical advances will be required before a large-scale, practical quantum computer can be achieved. Quantum Computing: Progress and Prospects provides an introduction to the field, including the unique characteristics and constraints of the technology, and assesses the feasibility and implications of creating a functional quantum computer capable of addressing real-world problems. This report considers hardware and software requirements, quantum algorithms, drivers of advances in quantum computing and quantum devices, benchmarks associated with relevant use cases, the time and resources required, and how to assess the probability of success.

Available in PDF, EPUB and Kindle. Book excerpt: The propagation of light in dispersive media is a subject of fundamental as well as practical importance. In recent years attention has focused in particular on how refractive index can vary with frequency in such a way that the group velocities of optical pulses can be much greater or much smaller than the speed of light in vacuum, or in which the refractive index can be negative. Treating these topics at an introductory to intermediate level, Fast Light, Slow Light and Left-Handed Light focuses on the basic theory and describes the significant experimental progress made during the past decade. The book pays considerable attention to the fact that superluminal group velocities are not in conflict with special relativity and to the role of quantum effects in preventing superluminal communication and violations of Einstein causality. It also explores some of the basic physics at the opposite extreme of very slow group velocities as well as stopped and regenerated light, including the concepts of electromagnetically induced transparency and dark-state polaritons. Another very active aspect of the subject discussed concerns the possibility of designing metamaterials in which the refractive index can be negative and propagating light is left-handed in the sense that the phase and group velocities are in opposite directions. The last two chapters are an introduction to some of the basic theory and consequences of negative refractive index, with emphasis on the seminal work carried out since 2000. The possibility that "perfect" lenses can be made from negative-index metamaterials-which has been perhaps the most controversial aspect of the field-is introduced and discussed in some detail.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Single atoms and atom-like defects in solids are promising platforms for realizing single photon sources and long-lived quantum memories, which are essential ingredients for the development of long-distance quantum networks. However, most atomic transitions are in the ultraviolet-NIR regions with wavelengths shorter than 1 μm, where propagation losses in optical fibers are prohibitively large. A notable exception is erbium ion, whose optical transition at 1.5 μm is in the "telecom band", allowing minimal fiber transmission losses. Isolating and addressing individual erbium ions using an optical interface have been elusive so far because of the poor emission rate of erbium due to the electric dipole-forbidden nature of its intra-4f optical transition. We report the observation of fluorescence from single erbium ions for the first time. We achieve this by integrating erbium ions in a low loss, small mode-volume silicon nanophotonic cavity and enhancing their emission rate by over two orders of magnitude.A crucial component of optically interfaced solid-state defects-based platforms is high-fidelity, projective measurement of the spin state, which is generally accomplished using fluorescence on an optical cycling transition. We demonstrate that the cavity modifies the local electromagnetic environment of an erbium ion (which otherwise lacks strong cycling transitions) and improves its cyclicity by greater than 100-fold, thus enabling high-fidelity single-shot quantum nondemolition readout of the ion's spin. We also identify dozens of spectrally distinct ions coupled to the same cavity. Combining an optical frequency-domain multiplexing technique and microwave rotations, we individually initialize, manipulate, and perform single-shot spin measurement of six such ions. Our approach is not limited by the spatial separation between individual ions and is readily scalable to tens or hundreds of ions.Finally, we demonstrate coherent coupling of an erbium electronic spin to a nearby nuclear spin and implement single-qubit and two-qubit gates on them, thus extending our platform's prowess as a quantum memory by making a long-lived nuclear spin register available for storage and retrieval of information. These results are a significant step towards realizing long-distance quantum networks by utilizing multiplexed quantum repeater protocols and deterministic quantum logic for photons based on a scalable silicon nanophotonics architecture.

Download or read book Modeling and Design of a Photonic Crystal Chip Hosting a Quantum Network Made of Single Spins in Quantum Dots that Interact Via Single Photons written by Hubert P. Seigneur and published by . This book was released on 2010 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, the prospect of a quantum technology based on a photonic crystal chip hosting a quantum network made of quantum dot spins interacting via single photons is investigated. The mathematical procedure to deal with the Liouville-Von Neumann equation, which describes the time-evolution of the density matrix, was derived for an arbitrary system, giving general equations. Using this theoretical groundwork, a numerical model was then developed to study the spatiotemporal dynamics of entanglement between various qubits produced in a controlled way over the entire quantum network. As a result, an efficient quantum interface was engineered allowing for storage qubits and traveling qubits to exchange information coherently while demonstrating little error and loss in the process; such interface is indispensable for the realization of a functional quantum network. Furthermore, a carefully orchestrated dynamic control over the propagation of the flying qubit showed high-efficiency capability for on-chip single-photon transfer. Using the optimized dispersion properties obtained quantum mechanically as design parameters, a possible physical structure for the photonic crystal chip was constructed using the Plane Wave Expansion and Finite-Difference Time-Domain numerical techniques, exhibiting almost identical transfer efficiencies in terms of normalized energy densities of the classical electromagnetic field. These promising results bring us one step closer to the physical realization of an integrated quantum technology combining both semiconductor quantum dots and sub-wavelength photonic structures.
