This book was released on 2015-12-30 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the research and development-related results of the “FIRST” Quantum Information Processing Project, which was conducted from 2010 to 2014 with the support of the Council for Science, Technology and Innovation of the Cabinet Office of the Government of Japan. The project supported 33 research groups and explored five areas: quantum communication, quantum metrology and sensing, coherent computing, quantum simulation, and quantum computing. The book is divided into seven main sections. Parts I through V, which consist of twenty chapters, focus on the system and architectural aspects of quantum information technologies, while Parts VI and VII, which consist of eight chapters, discuss the superconducting quantum circuit, semiconductor spin and molecular spin technologies. Readers will be introduced to new quantum computing schemes such as quantum annealing machines and coherent Ising machines, which have now arisen as alternatives to standard quantum computers and are designed to successfully address NP-hard/NP-complete combinatorial optimization problems, which are ubiquitous and relevant in our modern life. The book offers a balanced mix of theory-based and experimentation-based chapters written by leading researchers. Extensive information is provided on Quantum simulation, which focuses on the implementation of various many-body Hamiltonians in a well-controlled physical system, Quantum key distribution, Quantum repeaters and quantum teleportation, which are indispensable technologies for building quantum networks with various advanced applications and require far more sophisticated experimental techniques to implement.

Download or read book Theory of Nonclassical States of Light written by V.V. Dodonov and published by CRC Press. This book was released on 2003-03-13 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term 'nonclassical states' refers to the quantum states that cannot be produced in the usual sources of light, such as lasers or lamps, rather than those requiring more sophisticated apparatus for their production. Theory of Non-classical States of Light describes the current status of the theory of nonclassical states of light including many new and important results as well as introductory material and the history of the subject. The authors concentrate on the most important types of nonclassical states, namely squeezed, even/odd ('Schrodinger cat') and binomial states, including their generalizations. However, a review of other types of nonclassical is also given in the introduction, and methods for generating nonclassical states on various processes of light-matter interaction, their phase-space description, and the time evolution of nonclassical states in these processes is presented in separate chapters. This contributed volume contains all of the necessary formulae and references required to gain a good understanding of the principles and current status of the field. It will provide a valuable information resource for advanced students and researchers in quantum physics.

Download or read book The Physical Reality of Applied Quantum Optics written by Andre Vatarescu and published by Cambridge Scholars Publishing. This book was released on 2021-04-09 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book scrutinises, physically, the devices and components used in quantum optic experiments, revealing various, hitherto ignored, phenomena, including quantum Rayleigh spontaneous and stimulated emissions, the unavoidable parametric amplification of spontaneous emission, and the formation of groups of monochromatic photons in a high finesse cavity incorporating a quantum dot. The book also explores self-contained quantisation of the optical field without any harmonic oscillators leading to the dynamic and coherent number states, the intrinsic optical field of photons and their localised spatial distributions, and instantaneous and localised photon-dipole interactions by means of pure, dynamic and coherent number states. In addition, it looks at the quantum evolution and predictions being described by the Ehrenfest theorem, for any level of optical field excitation, in order to evaluate the expectation value of an operator in the context of a given set of pure wavefunctions, and identifies quantum phenomena at the level of single events and measurements with a space- and time-dependence, leading to quantum locality and realism. Overall, the book shows that there are no quantum optic “miracles” once the physically present effects are correctly identified.
Download or read book Theory and Simulations of Singly Resonant Optical Parametric Oscillators written by Domenico Cuozzo and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical parametric oscillators have been known and used for a long time as efficient sources of non-classical states of light both below threshold of oscillation, where they generate squeezed vacuum states and bi-partite entangled states, and above threshold of oscillation, where they generate intensity correlated twin beams. The singly-resonant cavity, where only one of the three field involved in the parametric amplification process is resonated (signal), is in principle a simpler configuration to realize experimentally but, to the best of our knowledge, theoretical investigations of non-classical features of the light from a singly-resonant OPO (SROPO) are missing. One of the reasons is that SROPOs operate with strongly non-degenerate frequencies while much of the literature on squeezing focuses on the degenerate or close to degeneracy cases. Recent interest in non-classical correlations of the strongly non-degenerate regime of parametric down-conversion makes the study of entanglement in SROPO important for the optimization of coherent sources with fluctuations below the shot-noise level. There are clear technical advantages for SROPO configurations: only resonance of the signal field has to be maintained, continuous temperature tuning and suppression of mode-hopping. As a matter of fact even if the doubly resonant configuration, where both the signal and the idler fields are resonated, has a much lower threshold pump power, the tuning behavior is complicated and is massively affected by changes of the crystal temperature or pump wavelength, causing the signal and idler wavelengths undergoing jumps, and the tuning is generally non-monotonous. This is because the operation wavelengths are determined primarily by the requirement for simultaneous resonance for signal and idler, and not only by a phase-matching condition as in the case of singly resonant configuration. It is in this spirit that in Chapter 4 we apply the input-output theory of optical cavities to formulate a quantum treatment of a continuous wave singly-resonant optical parametric oscillator. This case is mainly relevant to largely non-degenerate signal and idler modes. We show that both intensity and quadrature squeezing are present and that the maximum noise reduction below the standard quantum limit is the same at the signal and idler frequencies in a way similar to the doubly resonant case. As the threshold of oscillation is approached, however, the intensity-difference and quadrature spectra display a progressive line-narrowing which is absent in the balanced doubly-resonant case. By using the separability criterion for continuous variables, the signal-idler state is found to be entangled over wide ranges of the parameters. We show that attainable levels of squeezing and entanglement make singly-resonant configurations ideal candidates for two-colour quantum information processes because of their ease of tuning in experimental realizations. Another very interesting feature of SROPOs which, this time, has no counterpart in the doubly-resonant regime is described in Chapter 5 where model equations for the evolution of signal and idler pulses in a synchronously pumped optical parametric oscillator are derived and numerically integrated. A novel regime of giant sub-threshold pulses driven by quantum fluctuations is described through the analysis of stability eigenvalues, growth factors and pseudospectra. Subthreshold pulses driven by quantum fluctuations are found at various mirror reflectivities in the non degenerate regime where signal and idler have different group velocities. Giant sub-threshold pulses open the possibility of observing macroscopic continuous variable entanglement with nonclassical features. This important feature is peculiar to the singly-resonant configuration and has no counterpart in the doubly-resonant regime. Very interesting classical features of SROPOs light are investigated in Chapter 6 where we show that spatio-temporal dynamics of singly resonant optical parametric oscillators with external seeding displays hexagonal, roll and honeycomb patterns, optical turbulence, rogue waves and cavity solitons. We derive appropriate mean-field equations with a sinc2 non-linearity and demonstrate that off-resonance seeding is necessary and responsible for the formation of complex spatial structures via self-organization. We compare this model with those derived close to the threshold of signal generation and find that back-conversion of signal and idler photons is responsible for multiple regions of spatio-temporal self-organization when increasing the power of the pump field.
Download or read book Applied Research of Quantum Information Based on Linear Optics written by Xiaoye Xu and published by Springer. This book was released on 2016-03-31 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports on outstanding work in two main subfields of quantum information science: one involves the quantum measurement problem, and the other concerns quantum simulation. The thesis proposes using a polarization-based displaced Sagnac-type interferometer to achieve partial collapse measurement and its reversal, and presents the first experimental verification of the nonlocality of the partial collapse measurement and its reversal. All of the experiments are carried out in the linear optical system, one of the earliest experimental systems to employ quantum communication and quantum information processing. The thesis argues that quantum measurement can yield quantum entanglement recovery, which is demonstrated by using the frequency freedom to simulate the environment. Based on the weak measurement theory, the author proposes that white light can be used to precisely estimate phase, and effectively demonstrates that the imaginary part of the weak value can be introduced by means of weak measurement evolution. Lastly, a nine-order polarization-based displaced Sagnac-type interferometer employing bulk optics is constructed to perform quantum simulation of the Landau-Zener evolution, and by tuning the system Hamiltonian, the first experiment to research the Kibble-Zurek mechanism in non-equilibrium kinetics processes is carried out in the linear optical system.

Download or read book Quantum Fluctuations of Spacetime written by Lawrence B. Crowell and published by World Scientific. This book was released on 2005 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three key aspects of quantum gravity are considered in this book: phenomenology, potential experimental aspects and foundational theory. The phenomenology is the treatment of metric quantum fluctuations as torsional curves that deviate from classical expectations. This leads to possible experimental configurations that may detect such fluctuations. Most of these proposed experiments are quantum optical measurements of subtle quantum gravity effects in the interaction of photons and atoms. The foundational discussions attempt to find an substratum to string theories, which are motivated by the phenomenological treatment. Quantum gravity is not the quantization of general relativity, but is instead the embedding of quantum theory and gravitation into a more fundamental field theoretic framework.

Book excerpt: This volume presents six review articles devoted to various topics of current interest both in classical and in quantum optics. The first article, by S. Ya. Kilin, entitled "Quanta and Information", is concerned with a multidisciplinary subject which involves optics, information theory, programming and discrete mathematics. The second article, "Optical Solitons in Periodic Media with Resonant and Off-Resonant Nonlinearities", by G. Kurizki, A.E. Kozhekin, T. Optatrny and B. Malomed, reviews the properties of optical solitons in periodic nonlinear media. The article which follows deals with an effect and its inverse which is a manifestation of hindrance and enhancement, respectively, of the evolution of a quantum system by an external agent, such as a detection apparatus. The fourth article discusses the current status of a relatively new branch of physical optics, sometimes called singular optics. The next two articles respectively present a review of advances in two-photon interferometry and their relation to investigations of the foundations of quantum theory and an examination of transverse mode shaping and selection in laser resonators.
