Abstract Application of quantum theory in informatics and the creation of quantum information devices have revolutionary changed our idea about the information systems. It seems to us that the only question is that quantum computers will be introduced in the next decade or in some years later. Anyhow, we should prepare to teach a radically new paradigm, the quantum algorithms, in informatics. Quantum algorithm can be demonstrated with quantum simulators. The present paper shows an educational material, which facilitates the teaching of this new field. Besides summarising the basic concepts and methods of quantum informatics, the working of a quantum algorithm on a quantum simulator will be also illustrated with the discussion of an exciting quantum physical phenomenon (the teleportation).

Development of quantum informatics as a new field of computer science poses new challenges to teachers and students of computer science. Among others, very dynamic branches of quantum informatics are quantum programming languages and simulation of quantum systems.This article presents the program of the lecture: Quantum systems of informatics that is proposed to students of last semesters of computer science at Faculty of Automatic Control, Electronics and Computer Science of Silesian University of TechnologyThe objective of this lecture is to familiarize students with notions and elements of quantum informatics. Lecture will introduce basic mathematical concepts needed to operate a quantum mechanics apparatus and elements of information theory.Many tools useful in education of quantum informatics are presented. Most of them are based on Quantum Computer Language. They are the authors' original work.In the last section the examples of programs of laboratory classes, during which described software is used, are presented.
Quantum information processing and communication (QIPC) theory has developed recently very fast and brought a variety of interesting and important results of the great value also for the whole area of quantum physics. One can also say that the field of QIPC has been so far mainly theory driven and the experiments have been mostly done to show that it is indeed possible, and how difficult is to make it, what theory shows as possible. One of the main reasons for such a fast and successful development of the QIPC science is the fact that paradigms, models, concepts, value system, as well as methods and results of the (theoretical) informatics have been intensively used. The goal of this paper is to go behind this successful crusade and applications of the informatics for QIPC and to present, analyse and illustrate the main ideas, concepts, methods and tools that have been involved. All that should help more physics‐oriented researchers in QIPC to understand that in order to explore the quantum world, new paradigms, concepts, models and so on are now available, and they could and should be used, due to the progress in (theoretical) informatics. Our concentration will be not only on what has been achieved, but even more on the main new challenges. In doing that we will concentrate more on the backgrounds, motivations, goals and implications than on the very technical results.
Abstract Quantum teleportation plays a crucial role in information science for its property of completely secure transmission. It was first demonstrated as a means of transferring the quantum state. Later, it has been extended greatly in the field of quantum computing, quantum network, and quantum communication and other fields. The first part of this paper will talk briefly about the basic theory of quantum teleportation and the applications that have been achieved in recent years in both commercial and scientific purposes. Next, the results of current experiments and the challenges that should be overcome in the future will be presented. The final section will be a discussion about the development of quantum teleportation and its future implementations.
An essential overview of quantum information Information, whether inscribed as a mark on a stone tablet or encoded as a magnetic domain on a hard drive, must be stored in a physical object and thus made subject to the laws of physics. Traditionally, information processing such as computation occurred in a framework governed by laws of classical physics. However, information can also be stored and processed using the states of matter described by non-classical quantum theory. Understanding this quantum information, a fundamentally different type of information, has been a major project of physicists and information theorists in recent years, and recent experimental research has started to yield promising results. Quantum Approach to Informatics fills the need for a concise introduction to this burgeoning new field, offering an intuitive approach for readers in both the physics and information science communities, as well as in related fields. Only a basic background in quantum theory is required, and the text keeps the focus on bringing this theory to bear on contemporary informatics. Instead of proofs and other highly formal structures, detailed examples present the material, making this a uniquely accessible introduction to quantum informatics. Topics covered include: * An introduction to quantum information and the qubit * Concepts and methods of quantum theory important for informatics * The application of information concepts to quantum physics * Quantum information processing and computing * Quantum gates * Error correction using quantum-based methods * Physical realizations of quantum computing circuits A helpful and economical resource for understanding this exciting new application of quantum theory to informatics, Quantum Approach to Informatics provides students and researchers in physics and information science, as well as other interested readers with some scientific background, with an essential overview of the field.
Data communication technology has been actively researched for many years. As the conjunction of computer science and physics, quantum information brings brand new fundamentals with the term quantum communication. In this report we introduce a protocol in quantum communication called quantum teleportation, with explanations about its motivation and possible applications. Previous and current research achievements are summarised and evaluated in the authors’ perspective. After that a simulation program of quantum teleportation was implemented, tested and evaluated, giving constructive conclusions in the end.
Quantum technology is one of the most promising and challenging fields in contemporary science. Quantum computing, quantum cryptography, and more generally quantum information technologies claim that they, in the short term, will change our paradigm of classical computing and communications. Concepts such as duality, superposition, entanglement, teleportation and many others seem to be closer to magic or science fiction than to everyday human experience. However, herein lies also the unlimited power of human thought, which mathematics and physics help us to go beyond our immediate experience of the world. This book, oriented toward undergraduate students pursuing Bachelor’s Degrees in Engineering, draws on the experience of the authors during nearly ten years of work in this field. The book consists of a comprehensive list of exercises with increasing degrees of dificulty. Additional material such as solved problems and a basic compilation of theory is also included in each chapter. The list of topics, which include among others, quantum computing, quantum teleportation, superdense coding, quantum processors or quantum communication protocols, intended for opening doors that will motivate students to continue delving into the field of quantum technologies, which has only just begun to be explored.
