Introduction to Quantum Communication

Catalog description

Quantum communication is a profoundly interdisciplinary field, drawing from the realms of quantum physics, information theory, classical communication and networking, as well as optical engineering, among others. The primary objective of this course is to equip students with the foundational knowledge necessary to embark on future independent research endeavors. This comprehensive course is structured into three main components. The first segment thoughtfully encompasses vital concepts selectively curated from diverse disciplines, including linear algebra, quantum physics, classical and quantum optics, and optical fiber communication. By doing so, it enables students to construct a coherent understanding of both quantum and classical communication. The second part delves deeply into quantum entanglement, a pivotal element in numerous quantum communication protocols. This section elucidates the concept of entanglement, explores experimental techniques for its generation, and surveys its multifaceted applications. Recognizing the burgeoning concerns surrounding the security of classical cryptography in the face of potential quantum computer-based attacks, the final portion of the course is dedicated to quantum cryptography, a highly developed facet of quantum communication. Here, we will delve into various quantum protocols, accompanying security validations, and practical implementations. Additionally, advanced topics, such as quantum hacking and device-independent quantum cryptography, will be addressed.
