Book excerpt: The Brown-Twiss photon correlation effect is discussed in purely quantum-mechanical terms. It is shown that for states incoherent in the sense that the phase of the electric field component at each frequency is unknown, Bose commutation relations imply the existence of intensity beats at all the difference frequencies. This result does not depend on lack of knowledge of the number of photons at each frequency; the beats are obtained even if the state is known to be an n-photon one. This derivation is compared with the classical theories of Brown and Twiss, and Purcell. A discussion is also given of interference in spatially localized states.

Available in PDF, EPUB and Kindle. Book excerpt: Focusing on the unresolved debate between Newton and Huygens from 300 years ago, The Nature of Light: What is a Photon? discusses the reality behind enigmatic photons. It explores the fundamental issues pertaining to light that still exist today. Gathering contributions from globally recognized specialists in electrodynamics and quantum optics, the book begins by clearly presenting the mainstream view of the nature of light and photons. It then provides a new and challenging scientific epistemology that explains how to overcome the prevailing paradoxes and confusions arising from the accepted definition of a photon as a monochromatic Fourier mode of the vacuum. The book concludes with an array of experiments that demonstrate the innovative thinking needed to examine the wave-particle duality of photons. Looking at photons from both mainstream and out-of-box viewpoints, this volume is sure to inspire the next generation of quantum optics scientists and engineers to go beyond the Copenhagen interpretation and formulate new conceptual ideas about light–matter interactions and substantiate them through inventive applications.

Available in PDF, EPUB and Kindle. Book excerpt: Galileo Unbound traces the journey that brought us from Galileo's law of free fall to today's geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes. This book tells the history of spaces of expanding dimension and increasing abstraction and how they continue today to give new insight into the physics of complex systems. Galileo published the first modern law of motion, the Law of Fall, that was ideal and simple, laying the foundation upon which Newton built the first theory of dynamics. Early in the twentieth century, geometry became the cause of motion rather than the result when Einstein envisioned the fabric of space-time warped by mass and energy, forcing light rays to bend past the Sun. Possibly more radical was Feynman's dilemma of quantum particles taking all paths at once — setting the stage for the modern fields of quantum field theory and quantum computing. Yet as concepts of motion have evolved, one thing has remained constant, the need to track ever more complex changes and to capture their essence, to find patterns in the chaos as we try to predict and control our world.

Available in PDF, EPUB and Kindle. Book excerpt: This third edition, like its two predecessors, provides a detailed account of the basic theory needed to understand the properties of light and its interactions with atoms, in particular the many nonclassical effects that have now been observed in quantum-optical experiments. The earlier chapters describe the quantum mechanics of various optical processes, leading from the classical representation of the electromagnetic field to the quantum theory of light. The later chapters develop the theoretical descriptions of some of the key experiments in quantum optics. Over half of the material in this third edition is new. It includes topics that have come into prominence over the last two decades, such as the beamsplitter theory, squeezed light, two-photon interference, balanced homodyne detection, travelling-wave attenuation and amplification, quantum jumps, and the ranges of nonliner optical processes important in the generation of nonclassical light. The book is written as a textbook, with the treatment as a whole appropriate for graduate or postgraduate students, while earlier chapters are also suitable for final- year undergraduates. Over 100 problems help to intensify the understanding of the material presented.

Download or read book High order Interference of Photons in Thermal State written by Tao Peng and published by . This book was released on 2015 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superposition principle is one of the most challenging principles of quantum theory, especially in the multi-particle situation. In the language of quantum mechanics, the high-order quantum interference of multi-particle is the consequence of a superposition among different yet indistinguishable probability amplitudes, a non-classical entity corresponding to different yet indistinguishable alternative ways of producing a joint-detection event among distant detectors. In optics, the theory of multiphoton interference of quantum light such as entangled photons are well established and accepted. On the other hand, classical interpretation is frequently used to explain the multiphoton interference of classical light such as thermal light and pseudo-thermal light due to the historical reasons. In this dissertation, we will focus on the study of high-order interference of photons in thermal and pseudo-thermal states. Sunlight, as a typical thermal light, contains a large number of independent and randomly radiated point subsources resulted from the spontaneous atomic transitions. The atomic transitions emit subfields at random positions and times with random phases. The pseudo-thermal light, consisting of a laser beam and a rotating diffusing ground glass, which is frequently used in the lab, can also be modeled as containing a large number of independent and randomly radiated subsouces. A large number of subelds with random phases are then generated from those subsources at random positions and times. As we will show in the dissertation, despite the classical feature of the source, the high-order interference of photons in thermal and pseudo-thermal states can only be fully understood by quantum theory due to the nonlocal nature. We gave a new analysis of the statistical property of pseudo-thermal light based on the coherent state representation following the Glauber-Scully theory. We showed that the new model can describe the energy distribution of the pseudo-thermal light very well. We then showed a novel detection scheme called Photon-Number Fluctuation Correlation(PNFC) protocol, which measures the photon number fluctuation of each of the photodetectors and calculates the statistical correlation between them. This scheme was then applied to measure a 100% HBT correlation and the result can be explained as a nonlocal two-photon interference phenomenon. In additional, the PNFC protocol can be applied to thermal light ghost imaging resulting a 100% visibility ghost imaging measurement as well as high resolution. A set of experiments on the foundations of quantum theory including the delayed-choice quantum eraser experiment and Popper's experiment are then discussed. Nonlocal interference of randomly paired photons measured with the PNFC protocol is applied to explain the experimental results. The single photon picture can lead to paradoxes that can only be understood with the nonlocal interference of random thermal photon pairs with themselves. The nonlocal feature in the interference of photons in thermal state then inspired us to simulate Bell sate with photons in thermal state and extended the test of Bell s inequality to the fluctuation correlation measurement. Experimental observation of Bell correlation from the polarization measurement of thermal fields in photon-number fluctuations is reported, the experimental test of Bell's inequality in photon-number fluctuations is also reported. We then extended this scheme to the simulation of 3-photon GHZ state. The successful simulation of n-photon entangled states can lead to new perspective for quantum computing with thermal light. To demonstrate the potential of thermal light quantum computing, a simulation of the controlled-NOT gate operation is shown in the last part of the thesis. Throughout the dissertation, we showed that the phenomena of photons in thermal and pseudo-thermal state can be more easily and deeply understood by quantum mechanics.

Download or read book Coherence Properties of Electromagnetic Radiation written by Wang Chih-Chiang and published by . This book was released on 1964 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances are surveyed in research on the coherence properties of light and the concept is discussed of the photon degeneracy and the degree of coherence, which plays an important role in explaining many problems such as interference, beats, intensity fluctuations and so on. Since the processes of radiation occur at random the intensity of beat signal is determined by the correlation of the processes. Since photons are regarded as bosons there will be a corresponding term in the intensity fluctuations. From the experimental results available it appears that all coherent properties of light can be explained in terms of the basic concept of quantum mechanics. (Author).

Download or read book The Photon written by Trilochan Pradhan and published by Nova Publishers. This book was released on 2001 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about Maxwell's electromagnetic theory of light. First, it is a fully relativistic theory without having a non-relativistic limit. There arise many difficulties in quantising the electromagnetic field and in the physical interpretation of the wavefunction of its quanta. Further, the first quantisation of the Maxwell equations similar to quantisation of classical mechanics by the Schrodinger method, has not been discussed in most books on quantum mechanics. Second, the Maxwell field is the simplest gauge field possessing symmetry with respect to Poincare group of transformations in addition to scale, duality and special conformal transformations whose local versions give rise to new interaction of photons through new gauge fields. One of these gauge fields couples to the spin density of the photon and other particles and can bind fermion-antifermion pairs to give transverse photons. Another interesting aspect of the electromagnetic field is its coherence properties and their interpretation in terms of quantised theory.
