The article is devoted to quantum information (including its subdomains, namely: quantum communication, quantum computer, quantum cryptography), and its philosophical meaning. Paradox EPR, Bell’s inequality, phenomena of teleportation are discussed of a philosophical point of view. Quantum mechanical nonlocal correlations are interpreted as topological inseparabilities.

The book is devoted to the contemporary stage of quantum mechanics – quantum information, and especially to its philosophical interpretation and comprehension: the first one of a series monographs about the philosophy of quantum information. The second will consider Be l l ’ s inequalities, their modified variants and similar to them relations. The beginning of quantum information was in the thirties of the last century. Its speed development has started over the last two decades. The main phenomenon is entanglement. The subareas are quantum computer, quantum communication (and teleportation), and quantum cryptography. The book offers the following main conceptions, theses and hypotheses: – dualistic Phythagoreanism as a new kind among the interpretations of quantum mechanics and information: arithmetical, logical, and metamathematical one; – Gödel ’ s first incompleteness theorem is an undecidable proposition, and consequently the second one,too. – a partial rehabilitation of Hilbert ’ s program for the self-foundation of mathematics; – the dual-foundation of mathematics; – Skolemian relativity between: Cantor ’s kinds of infinity, finiteness and infinity, discreteness and continuity, completeness and incompleteness, etc.; – information is a physical quantity representing the non-reducibility of a system to its parts, particularly nonaddtivity; – there exist pure relations «by itself», which cannot be reduced to predications; – energy conservation can and should be generalized; – Einstein’ s «general covariance» or «principle of relativity» can and should be generalized to cover discrete morphisms where the notion of velocity does not make sense.
In this article we are willing to give some first steps to quantum mechanics and a motivation of quantum mechanics and its interpretation for undergraduate students not from physics. After a short historical review in the development we discuss philosophical, physical and mathematical interpretation. We define local realism, locality and hidden variable theory which ends up in the EPR paradox, a place where questions on completeness and reality comes into play. The fundamental result of the last century was maybe Bell's that states that local realism is false if quantum mechanics is true. From this fact we can obtain the so called Bell inequalities. After a didactic example of the fact what these inequalities means we describe the key concept of quantum entanglement motivated here by quantum information theory. Also classical entropy and von Neuman entropy is discussed.
Quantum entanglement, a quintessential feature of quantum mechanics, has profound implications on our understanding of the fundamental nature of reality. This phenomenon, in which quantum particles exhibit correlations that defy classical intuition, has captivated physicists and philosophers alike. The existence of nonlocal correlations, a hallmark of entanglement, challenges the principles of local realism and calls into question our notions of causality and locality. This paper explores the theoretical foundations, experimental evidence, and interpretations surrounding quantum entanglement and nonlocal correlations. It delves into the historical context, highlighting the pioneering work of physicists such as Einstein, Podolsky, Rosen, and Bell, whose contributions paved the way for our current understanding of this enigmatic concept. The paper also examines the potential applications of entanglement in fields such as quantum computing, cryptography, and communication, underscoring its technological significance. Furthermore, it discusses the philosophical implications of nonlocal correlations, shedding light on the ongoing debates surrounding the interpretation of quantum mechanics and the nature of reality itself. Keywords: Quantum entanglement, Nonlocal correlations, Local realism, Causality, Locality, Quantum mechanics, Experimental evidence, Theoretical foundations, Einstein-Podolsky-Rosen (EPR) paradox, Bell's theorem, Quantum computing.
Quantum information theory represents a rich subject of discussion for those interested in the philosphical and foundational issues surrounding quantum mechanics for a simple reason: one can cast its central concerns in terms of a long-familiar question: How does the quantum world differ from the classical one? Moreover, deployment of the concepts of information and computation in novel contexts hints at new (or better) means of understanding quantum mechanics, and perhaps even invites re-assessment of traditional material conceptions of the basic nature of the physical world. In this paper I review some of these philosophical aspects of quantum information theory, begining with an elementary survey of the theory, seeking to highlight some of the principles and heuristics involved. We move on to a discussion of the nature and definition of quantum information and deploy the findings in discussing the puzzles surrounding teleportation. The final two sections discuss, respectively, what one might learn from the development of quantum computation (both about the nature of quantum systems and about the nature of computation) and consider the impact of quantum information theory on the traditional foundational questions of quantum mechanics (treating of the views of Zeilinger, Bub and Fuchs, amongst others).

Quantum entanglement, the phenomenon whereby two or more quantum systems exhibit correlations that cannot be explained by any local hidden-variable theory, has evolved from a philosophical curiosity debated by Einstein, Podolsky, and Rosen in 1935 into the foundational resource of an emerging technological revolution. This narrative review traces the conceptual development of entanglement from the EPR paradox through Bell's theorem, the experimental violation of Bell inequalities, and the emergence of quantum information science as a unifying framework. Drawing on the original EPR argument, Bell's seminal 1964 theorem, the experimental work of Aspect et al., the quantum information synthesis of Nielsen and Chuang, the review of entanglement theory by Horodecki et al., and the foundational perspectives of Brukner and Zeilinger, the review covers the mathematical characterization of entanglement, its role in quantum computation and quantum cryptography, and the ongoing debate about the interpretation of quantum mechanics that entanglement continues to fuel.
