"Quantum Interferometry in Phase Space" is primarily concerned with quantum-mechanical distribution functions and their applications in quantum optics and neutron interferometry. In the first part of the book, the author describes the phase-space representation of quantum optical phenomena such as coherent and squeezed states. Applications to interferometry, e.g. in beam splitters and fiber networks, are also presented. In the second part of the book, the theoretical formalism is applied to neutron interferometry, including the dynamical theory of diffraction, coherence properties of superposed beams, and dephasing effects.

One century after the discovery of the quanta and their basic properties, the interdisciplinary science of ´Quantum Interferometry´ retains its original role of being the crossing road between theoretical analysis and interpretation, physics and philosophy, settlement of principles and the prospect for new endeavours. In recent decades the technological achievements have allowed the realization of many earlier gedanken experiments. This has cleared up many issues of previous debate on the foundations by opening, at the same time, new fields of investigation on still subtler aspects of the theory. Furthermore, this evolution has stimulated the birth of new important research of more technological character aimed at the development of practical devices of future general interest, e.g. the new sciences of ´Atom–Optics´, the ´Cavity QED´ in cavities and microcavities, solid–state nanostructures and ´Quantum Computation´. This book collects the texts of lectures given by foremost experts concerning the various modern aspects of ´Quantum Interferometry´ at an Adriatico Conference held, with the same title, in Trieste in March 1996.

The quantum interference of de Broglie matter waves is probably one of the most startling and fundamental aspects of quantum mechanics. It continues to tax our imaginations and leads us to new experimental windows on nature. Quantum interference phenomena are vividly displayed in the wide assembly of neutron interferometry experiments, which have been carried out since the first demonstration of a perfect silicon crystal interferometer in 1974. Since the neutron experiences all four fundamental forces of nature (strong, weak, electromagnetic, and gravitational), interferometry with neutrons provides a fertile testing ground for theory and precision measurements. Many Gedanken experiments of quantum mechanics have become real due to neutron interferometry. Quantum mechanics is a part of physics where experiment and theory are inseparably intertwined. This general theme permeates the second edition of this book. It discusses more than 40 neutron interferometry experiments along with their theoretical motivations and explanations. The basic ideas and results of interference experiments related to coherence and decoherence of matter waves and certain post-selection variations, gravitationally induced quantum phase shifts, Berry`s geometrical phases, spinor symmetry and spin superposition, and Bell's inequalities are all discussed and explained in this book. Both the scalar and vector Aharonov-Bohm topological interference effects and the neutron version of the Sagnac effect are presented in a self-contained and pedagogical way. Interferometry with perfect crystals, artificial lattices, and spin-echo systems are also topics of this book. It includes the theoretical underpinning as well as connections to other areas of experimental physics, such as quantum optics, nuclear physics, gravitation, and atom interferometry. The observed phase shifts due to the Earth's gravity and rotation indicate a close connection to relativity theory. Neutron interferometry can be considered as a central technique of quantum optics with massive particles. It has stimulated the development of interferometry with atoms, molecules and clusters. The book is written in a style that will be suitable at the senior undergraduate and beginning of graduate level. It will interest and excite many students and researchers in neutron, nuclear, quantum, gravitational, optical, and atomic physics. Lecturers teaching courses in modern physics and quantum mechanics will find a number of interesting and historic experiments they may want to include in their lectures.

This dissertation details a series of experiments conducted at the few-photon level involving quantum entanglement and quantum interferometry. The dissertation begins with the presentation of the quantum optical realization of a thought experiment proposed by Lucien Hardy that demonstrates a striking contrast between the predictions of quantum mechanics and those of local realistic theories. The experiment uses only pairs of particles in a non-maximally entangled state to produce a nonstatistical contradiction between the quantum mechanical and local realistic predictions, thereby surpassing Bell and GHZ-type inequality tests. This is followed by a description of the process of parametric down-conversion along with the demonstration of two separate experimental techniques that use quantum interference to improve the quality of polarization entanglement in photon pairs. The work with photon pairs is extended to several experiments involving multiple pairs of photons. These experiments include a scheme to prepare heralded, path-entangled states from a down-conversion source, as well as demonstrations of both symmetric and antisymmetric behavior by composite states of photons. The theory of multiple pair production is presented to explain the quality of interference in these experiments. Finally, novel multiphoton detectors are employed to demonstrate phase measurement sensitivity at the standard-quantum limit with a coherent state interferometer. For the first time phase-independent sensitivity is achieved through the use of a Bayesian statistical analysis of the photodetector data. The result of phase-independent sensitivity is also demonstrated in an experiment using ordinary photodiode detectors.

Since atom interferometers were first realized about 20 years ago, atom interferometry has had many applications in basic and applied science, and has been used to measure gravity acceleration, rotations and fundamental physical quantities with unprecedented precision. Future applications range from tests of general relativity to the development of next-generation inertial navigation systems. This book presents the lectures and notes from the Enrico Fermi school "Atom Interferometry", held in Varenna, Italy, in July 2013. The aim of the school was to cover basic experimental and theoretical aspects and to provide an updated review of current activities in the field as well as main achievements, open issues and future prospects. Topics covered include theoretical background and experimental schemes for atom interferometry; ultracold atoms and atom optics; comparison of atom, light, electron and neutron interferometers and their applications; high precision measurements with atom interferometry and their application to tests of fundamental physics, gravitation, inertial measurements and geophysics; measurement of fundamental constants; interferometry with quantum degenerate gases; matter wave interferometry beyond classical limits; large area interferometers; atom interferometry on chips; and interferometry with molecules. The book will be a valuable source of reference for students, newcomers and experts in the field of atom interferometry.

The work in this thesis was a part of the experiment of squeezed light injection into the LIGO interferometer. The work first discusses the detailed design of the squeezed light source which would be used for the experiment. The specific design is the doubly-resonant, traveling-wave bow-tie cavity squeezed light source with a new modified coherent sideband locking technique. The thesis describes the properties affecting the squeezing magnitudes and offers solutions which improve the gain. The first part also includes the detailed modeling of the back-scattering noise of a traveling Optical Parametric Oscillator (OPO). In the second part, the thesis discusses the LIGO Squeezed Light Injection Experiment, undertaken to test squeezed light injection into a 4km interferometric gravitational wave detector. The results show the first ever measurement of squeezing enhancement in a full-scale suspended gravitational wave interferometer with Fabry-Perot arms. Further, it showed that the presence of a squeezed-light source added no additional noise in the low frequency band. The result was the best sensitivity achieved by any gravitational wave detector. The thesis is very well organized with the adequate theoretical background including basics of Quantum Optics, Quantum noise pertaining to gravitational wave detectors in various configurations, along with extensive referencing necessary for the experimental set-up. For any non-experimental scientist, this introduction is a very useful and enjoyable reading. The author is the winner of the 2013 GWIC Theses Prize.
