From optical bistability towards optical computing

Paul Mandel, Stuart D. Smith, Brian S. Wherrett

Published Jan 1, 1987• 49 citations

Abstract

This book describes a programme of research at both basic and applied levels on the subject of optical bistability, and the devices that can be derived using the physical principles inherent to this phenomenon. A highlight of the volume is the description of research on giant optical nonlinearities and the realization of the first all-optical circuits, The European Joint Optical Bistability (EJOB) project, whose work is represented in this volume, has successfully demonstrated an all-optical digital circuit in the form of a classical finite state machine. This proves the scientific feasibility of a new family of computers which rival, and which will eventually exceed, the maximum processing capability attainable with electronics technology. These impressive advances are at least on part due to the unique collaboration fostered by EJOB, bringing together Belgian, German, British, Italian, French and Irish scientists. The result is a book capturing the massive potential of European science and technology.

Frontiers in quantum optics

Sarben Sarkar, Edward R. Pike

The field of quantum optics has progressed rapidly in the last twenty five years with the advent of the laser. Over much of this period the phenomena studied could be described adequately by semiclassical treatments. Quite recently however, there has been a revival of interest in genuinely quantum mechanical effects. The Malvern Symposium of December 1985 brought together world experts for a meeting which concentrated largely on these quantum effects. The presentations in this unique meeting combine review material with the very latest results and so will be of value to students of quantum optics and measurement theory at all levels. The first articles cover the exciting topic of the generation of squeezed states of light in the laboratory, and their possible uses. Experimental success has been long sought and very recently attained. The reader will find presented the state of the art in this field. Next to lasing itself, optical bistability has been the most widely studied phenomenon in quantum optics, largely for its technological promise. However, it also provides a fundamental system to study quuantum effects. Recent theoretical studies of optical bistability with small numbers of atoms are surveyed. In such situations quantum features such as antibunching become significant, and the articles in this volume should be a guide to those venturing into this challenging area. In other articles discussions of fluctuations from other noise sources and instabilities in optical bistabilty are presented in a clear and interesting way. Perhaps the least classical state on quantum optics is that describing a single photon. Recent experiments which produce such states are reviewed. A theoretical review of the photon together with some new material is given which delves deeply into relativistic quantum field theory in order to describe the concept of weakly localised photon states. The material here is very rarely presented in the context of quantum optics. The history of the theory of the quantum fluctuations in a laser is then reviewed. An off-shoot of this theory is the study of quantum chaos in dissipative systems and recent results in this new area are given in a succeeding article. There are further stimulating articles on Rydberg atom systems and quantum electrodynamics. The volume ends with an entertaining and incisive study of quantum measurement problems, such as the Schrodinger cat papadox, using concepts and measuring devices found in quantum optics.other_titles

Optical Bistability

Jia‐Ming Liu

Suitable for both graduate and senior undergraduate students, this textbook offers a logical progression through the underlying principles and practical applications of nonlinear photonics. Building up from essential physics, general concepts, and fundamental mathematical formulations, it provides a robust introduction to nonlinear optical processes and phenomena, and their practical applications in real-world devices and systems. Over 45 worked problems illustrate key concepts and provide hands-on models for students, and over 160 end-of-chapter exercises supply students with plenty of scope to master the material. Accompanied by a complete solutions manual for instructors, including detailed explanations of each result, and drawing on the author's 35 years of teaching experience, this is the ideal introduction to nonlinear photonics for students in electrical engineering.

The European quantum technology flagship: Paving the way for the second quantum revolution

J. Mlynek

Over the past two years, a comprehensive strategy for quantum technology in Europe has been created by the joint effort of academia and the business sector with community support from all over the continent.By building on that, Europe is making the next big leap with the first wave of pioneering projects launched in October 2018, sending a clear global signal that we will do our very best to retain the historic lead in quantum sciences.Building on Europe's rich scientific heritage and the strong quantum community, the Quantum Technology Flagship was launched by the European Commission with a €1 billion budget.The ambitious initiative will support over 5,000 of Europe's leading researchers over the next ten years.As announced during the official kick-off in October 2018, 20 projects worth €132 million will be funded in the initial 3-year phase via the European Commission's Horizon 2020 programme.A solid indicator of success is the staggering number of proposals submitted for the first Flagship call: 140 consortia have requested almost five times the available budget.Over the decade-long course of the Flagship, over 150 projects are expected to be realised.The total €1 billion funding will foster the entire quantum value chain from basic research to industrialisation, thus bringing together researchers and the business sector.Four research and innovation domains will simultaneously be the focus of the European efforts: Communication, Computation, Simulation, as well as Sensing and Metrology represent the major applied areas in the field, which will also be advanced by breakthrough discoveries in the fifth, underlying domain of Basic Science.The Communication domain will foster the development of cheap, compact, faster and more secure random number generators, as well as components and systems for continuous variable quantum communication.Parallel to these, a blueprint for the pan-European Quantum Internet shall be created by developing all essential subsystems and giving the first experimental demonstration.Within Computing, two projects aim to develop quantum computers that are competitive with today's state-of-the-art supercomputers, either by realising a fully-automated ion-trap quantum computer or by building a machine with up to 100 superconducting qubits.The Simulation domain will push the already well-advanced neutral atom and ion-based quantum simulation platforms and address quantum annealing or optimization problems through full programmability.Parallel to that a quantum simulator platform made of ultracold atoms will be created, engineering a new generation of quantum cascade laser frequency combs characterized by non-classical emission and entanglement among the comb nodes.The Sensing domain will see the development of novel and compact atomic clocks, as well as the exploitation of atom-like defects in diamond to develop a variety of sensors and in magnetic resonance imaging to improve the detection of cardiovascular diseases.Furthermore, it will support combining state-of-the-art quantum sensor physics with MEMS atomic vapor cells, allowing for high-volume, high-reliability, low-cost deployment.Finally, within the domain of Basic Science, seven projects will investigate a variety of topics and technologies, with a focus on microfabricated devices and photonic systems.Enhancing capabilities in quantum technologies will help create a lucrative knowledge-based industry, leading to long-term economic, scientific and societal benefits, while delivering novel ideas, tools, components, materials, methods and processes.By funding ground-breaking projects, the Flagship will enable "quantum leaps" in technology development over the next decade, which in turn will lead to establishing markets within and wealth creation even beyond the European quantum ecosystem.Currently Europe is still at the leading edge of quantum technologies worldwide.However, this might rapidly change, as the demand for technology and talent is increasing at an unprecedented pace around the globe due to the promising future of quantum applications.Governments of industry powerhouse nations like the USA or China, as well as corporations such as Google, IBM, Microsoft, Alibaba, and Tencent are already investing substantial amounts to unleash quantum technologies' potential.
