Quantum Shannon Theory

Quantum Shannon Theory extends classical information theory to quantum systems, exploring how information is transmitted and processed using quantum mechanics. It examines the limits of communication, encoding, and decoding of quantum information, taking into account phenomena like superposition and entanglement. Key concepts include quantum capacity, which measures how much information can be reliably transmitted over a quantum channel, and the study of error correction methods to mitigate noise in quantum communication. This theory is fundamental to advancements in quantum computing, cryptography, and secure communication, as it provides the framework for understanding the behavior of information at a quantum level.
