Quantum Key Distribution: An Introduction with Exercises

Fabian Laudenbach, Christoph Pacher, Chi‐Hang Fred Fung +6 more

Quantum key distribution allows two parties to establish an encryption key that, by the laws of physics, no other party can have knowledge on and therefore enables information-theoretic communication security. In particular, quantum key distribution with continuous variables (CV-QKD) represents a way to exercise quantum cryptography at a high technological readiness level taking advantage of the leading-edge technological infrastructure provided by the telecom industry. The review by Fabian Laudenbach et al. (article number 1800011) provides a detailed introduction to the mathematical tools and relations required for the security analysis of CV-QKD and particularly deals with the effects of necessarily imperfect hardware components.

This book offers an accessible and engaging introduction to quantum cryptography, assuming no prior knowledge in quantum computing. Essential background theory and mathematical techniques are introduced and applied in the analysis and design of quantum cryptographic protocols. The title explores several important applications such as quantum key distribution, quantum money, and delegated quantum computation, while also serving as a self-contained introduction to the field of quantum computing. With frequent illustrations and simple examples relevant to quantum cryptography, this title focuses on building intuition and challenges readers to understand the basis of cryptographic security. Frequent worked examples and mid-chapter exercises allow readers to extend their understanding, and in-text quizzes, end-of-chapter homework problems, and recommended further reading reinforce and broaden understanding. Online resources available to instructors include interactive computational problems in Julia, videos, lecture slides, and a fully worked solutions manual.
