Available in PDF, EPUB and Kindle. Book excerpt: This book reviews progress towards quantum simulators based on photonic and hybrid light-matter systems, covering theoretical proposals and recent experimental work. Quantum simulators are specially designed quantum computers. Their main aim is to simulate and understand complex and inaccessible quantum many-body phenomena found or predicted in condensed matter physics, materials science and exotic quantum field theories. Applications will include the engineering of smart materials, robust optical or electronic circuits, deciphering quantum chemistry and even the design of drugs. Technological developments in the fields of interfacing light and matter, especially in many-body quantum optics, have motivated recent proposals for quantum simulators based on strongly correlated photons and polaritons generated in hybrid light-matter systems. The latter have complementary strengths to cold atom and ion based simulators and they can probe for example out of equilibrium phenomena in a natural driven-dissipative setting. This book covers some of the most important works in this area reviewing the proposal for Mott transitions and Luttinger liquid physics with light, to simulating interacting relativistic theories, topological insulators and gauge field physics. The stage of the field now is at a point where on top of the numerous theory proposals; experiments are also reported. Connecting to the theory proposals presented in the chapters, the main experimental quantum technology platforms developed from groups worldwide to realize photonic and polaritonic simulators in the laboratory are also discussed. These include coupled microwave resonator arrays in superconducting circuits, semiconductor based polariton systems, and integrated quantum photonic chips. This is the first book dedicated to photonic approaches to quantum simulation, reviewing the fundamentals for the researcher new to the field, and providing a complete reference for the graduate student starting or already undergoing PhD studies in this area.

Download or read book Symmetry in Quantum Optics Models written by Lucas Lamata and published by MDPI. This book was released on 2019-11-21 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prototypical quantum optics models, such as the Jaynes–Cummings, Rabi, Tavis–Cummings, and Dicke models, are commonly analyzed with diverse techniques, including analytical exact solutions, mean-field theory, exact diagonalization, and so on. Analysis of these systems strongly depends on their symmetries, ranging, e.g., from a U(1) group in the Jaynes–Cummings model to a Z2 symmetry in the full-fledged quantum Rabi model. In recent years, novel regimes of light–matter interactions, namely, the ultrastrong and deep-strong coupling regimes, have been attracting an increasing amount of interest. The quantum Rabi and Dicke models in these exotic regimes present new features, such as collapses and revivals of the population, bounces of photon-number wave packets, as well as the breakdown of the rotating-wave approximation. Symmetries also play an important role in these regimes and will additionally change depending on whether the few- or many-qubit systems considered have associated inhomogeneous or equal couplings to the bosonic mode. Moreover, there is a growing interest in proposing and carrying out quantum simulations of these models in quantum platforms such as trapped ions, superconducting circuits, and quantum photonics. In this Special Issue Reprint, we have gathered a series of articles related to symmetry in quantum optics models, including the quantum Rabi model and its symmetries, Floquet topological quantum states in optically driven semiconductors, the spin–boson model as a simulator of non-Markovian multiphoton Jaynes–Cummings models, parity-assisted generation of nonclassical states of light in circuit quantum electrodynamics, and quasiprobability distribution functions from fractional Fourier transforms.

Download or read book Quantum Simulation written by Chad Orzel and published by Institute of Physics Publishing. This book was released on 2017-06-12 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most active areas in atomic, molecular and optical physics is the use of ultracold atomic gases in optical lattices to simulate the behaviour of electrons in condensed matter systems. The larger mass, longer length scale, and tuneable interactions in these systems allow the dynamics of atoms moving in these systems to be followed in real time, and resonant light scattering by the atoms allows this motion to be probed on a microscopic scale using site-resolved imaging. This book reviews the physics of Hubbard-type models for both bosons and fermions in an optical lattice, which give rise to a rich variety of insulating and conducting phases depending on the lattice properties and interparticle interactions. It also discusses the effect of disorder on the transport of atoms in these models, and the recently discovered phenomenon of many-body localization. It presents several examples of experiments using both density and momentum imaging and quantum gas microscopy to study the motion of atoms in optical lattices. These illustrate the power and flexibility of ultracold-lattice analogues for exploring exotic states of matter at an unprecedented level of precision.

Download or read book Quantum Precision Measurement and Cold Atom Physics written by Jingbiao Chen and published by Frontiers Media SA. This book was released on 2022-09-23 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since the invention of the cesium atomic clock in 1955, quantum frequency standards have seen considerable development over the decades, as a representative of quantum precision measurement. The progress in frequency measurements achieved in the past allowed one to perform quantum precision measurements of other physical and technical quantities with unprecedented precision, whenever they could be traced back to a frequency measurement. Using atomic transitions as frequency reference, quantum frequency standards are far less susceptible to external perturbations, and the identity of microscopic particles allows easy replication of a quantum standard with the same frequency. With laser cooling and trapping, cold atomic ensembles eliminate Doppler shift broadening, and have become the go-to quantum reference when precision and new physics are pursued. The advancement of laser cooling and cold atom physics, in addition to novel physical matter states such as Bose-Einstein Condensation, give rise to new experimental techniques in quantum precision measurement, especially quantum frequency standards, such as cesium fountain clocks dictating the SI second, as well as optical lattice clocks and single-ion optical clocks pushing the frontier of quantum metrology. Other areas of quantum metrology, such as gravitometers and magnetometers, also benefit greatly from cold atoms. For practical applications, quantum frequency standards are usually required to be compact and portable, and thermal atoms in the form of atomic beams or vapor cells are utilized. Commercially available quantum frequency standards such as cesium beam clocks or rubidium clocks have become the cornerstone of navigation and timekeeping. Compact optical clocks based on various laser spectroscopic techniques have also been developed. As researchers strive to break through the limits of accurate quantum measurement and atomic temperature, new fields such as precise measurement, quantum computing and quantum simulation based on cold atoms are further opened up, and challenges still exist to explore new physical phenomena in the field of cold atoms. In honor of Prof. Yiqiu Wang on the occasion of his 90th birthday, the main goal of this Research Topic is to provide a platform to exhibit the recent achievements and reveal the future challenges in quantum precision measurement, as well as studies of cold atom physics with quantum metrology, closely related to the long-term scientific research areas of Prof. Yiqiu Wang. Both Original Research and Review articles are encouraged. Topics of interest to this collection include, but are not limited to: • Quantum precision measurements • Microwave atomic clocks and their applications • Optical frequency standards, laser spectroscopy, and their applications • Quantum measurement based on cold atom • Quantum computation and quantum simulation based on cold atom

This book was released on 2012-10-06 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
