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 n

During the last decades frontieres in various branches of physics have been investigated, especially for describing coherent effects, with very similar methodologies. In particular, the quantum-like formalism has recently received a great deal of attention for describing a number of 'classical topics', such as charged particle beam optics and dynamics in accelerating machines, plasma physics, nonlinear optics, transmission lines, solid state physics. On the other hand, proper quantum models that have been applied to coherent correlated states, squeezed states, macroscopic quantum coherence in superconductivity, superradiance in condensed matter, stochastic mechanics, have also been recently developed in way fully similar to the one used for quantum-like models. The quantum-like approach seems, therefore, to form a common basis for understanding the observations in many diverse field of science.This volume collects very significant examples of these common methodologies that have been given by various quantum-like approaches for describing numerious physical scenarios in the above branches of physics.

This volume contains the proceedings of the Third International Conference on Quantum Communication and Measurement. The series of international conferences on quantum communication and measurement was established to encourage scientists working in the interdisciplinary research fields of quantum communication science and technology. The first such conference, organized by C. Benjaballah and O. Hirota under the title "Quantum Aspects of Optical Communication," assembled approximately 80 researchers in Paris in 1990. The second conference, held in Nottingham in 1994, was organized by V. P. Belavkin, R. L. Hudson, and O. Hirota and attracted about 130 participants from 22 countries. The present conference, organized by O. Hirota, A. S. Holevo, C. M. Caves, H. P. Yuen, and L. Accardi, was heldSeptember 25-30, 1996, in Fuji-Hakone Land, Japan, andjnvolved about 120 researchers from 15 countries. The topics at this third conference included the foundations of quantum communi cation and information theory, quantum measurement theory, quantum cryptography and quantum computation, quantum devices and high-precision measurements, gener ation of nonclassical light, and atom optics. Special emphasis was placed on bringing together research workers in experimental and engineering fields of quantum commu nication and quantum computing and theoreticians working in quantum measurement and information theory. Nineteen plenary and parallel sessions and one poster ses sion were organized, at which a total of 82 papers were presented. Interesting and stimulating scientific discussions took place between and after sessions as well as in the evenings.

This book reports on cutting-edge research concerning social practices. Merging perspectives from various disciplines, including philosophy, biology, psychology and cognitive science, and economy, it discusses theoretical aspects of social behavior along with models to investigate them, and presenting key case studies as well. Further, it describes concepts related to habits, routines, and rituals and examines important features of human action, such as intentionality and choice, exploring the influence of specific social practices in different situations. Based on a workshop held on April 2022 at the World Congress on Universal Logic (UNILOG 22), in Crete, and including additional invited chapters, the book offers fresh insights into the fields of social practice and the cognitive, computational, and philosophical tools to understand them.

In The Foundations of Quantum Mechanics - Historical Analysis and Open Questions, leading Italian researchers involved in different aspects of the foundations and history of quantum mechanics are brought together in an interdisciplinary debate. The book therefore presents an invaluable overview of the state of Italian work in the field at this moment, and of the open problems that still exist in the foundations of the theory. Audience: Physicists, logicians, mathematicians and epistemologists whose research concerns the historical analysis of quantum mechanics.
