Basic Concepts

Holography in high-energy theory means a duality between gravity and quantum physics. A popular catchphrase is “gravity = quantum physics”. In this duality, the spacetime dimension of gravity theory is higher than the dimension of quantum theory, so the duality is dubbed “holography”. In this article, we explain, in chronological order, the basic concepts of holography and its various applications to quantum chromodynamics, condensed matter physics, and quantum information.

We have seen that there is an intimate relationship between probability and information. The values we assign to probabilities depend on the information available, and information is a function of probabilities. This connection makes it inevitable that information will be an important concept in any statistical theory, including thermodynamics and, of course, quantum physics. The probabilistic interpretation of quantum theory has probability amplitudes rather than probabilities as the fundamental quantities. This feature, together with the associated superposition principle, is responsible for intrinsically quantum phenomena and gives quantum information theory its distinctive flavour. We shall see that the quantum rules for dynamical evolution and measurement, together with the existence of entangled states, have important implications for quantum information. They also make it possible to perform tasks which are either impractical or impossible within the classical domain. In describing these we shall make extensive use of simple but fundamental ideas in quantum theory. This chapter introduces the mathematical description of quantum physics and the concepts which will be employed in our study of quantum information.
