Quantum Information Theory

Course Number: ECE 623, PHYSICS 623

Fall  2023


This course is mainly focused on Quantum Information theory, and more specifically, Quantum Shannon theory. In the light of quantum mechanics, classical  concepts such as information, bit, entropy, mutual information, data compression, and channel capacity, should be modified to take into account quantum effects. Similar to its classical version, the primary motivation for quantum information theory is the theory of communication. Interestingly, it turns out that by taking advantage of quantum phenomena, such as information-disturbance principle, distant parties can communicate with a level of privacy, which is unattainable classically.

Applications of this field are not limited to the communication theory. Quantum information theory has found applications in different areas of physics, from topological order, and many-body systems to quantum thermodynamics,  quantum gravity and black holes. Also, the ideas and tools developed in this theory are crucial for understanding quantum noise and decoherence. Furthermore, this theory provides a framework for understanding and quantifying entanglement and other quantum resources such as coherence.
