Quantum Cryptography by Pearson

As quantum computers continue to advance, they will eventually be capable of breaking many of the encryption algorithms we depend on today for banking, healthcare, cloud services, and personal communication. To stay ahead of these threats, organizations must begin preparing now with quantum-resistant security strategies. In this course, cybersecurity expert, Dr. Chuck Easttom explains how the powerful laws of quantum mechanics can be leveraged to protect information in ways conventional encryption never could. Imagine sending a secret message protected by a lock that instantly alerts you—and destroys the message—if anyone even tries to tamper with it. That's essentially what quantum cryptography offers.

Discover how quantum cryptography and quantum-safe encryption work, why these matter, and how technologies like quantum key distribution (QKD) can secure information over untrusted channels. Find out how two parties can exchange secret keys with built-in tamper detection, like sending a message in invisible ink that only the intended recipient can reveal. Review high-level concepts with practical examples that have real-world relevance, including asymmetric encryption algorithms, mitigating the risks of emerging threats, quantum-resistant (post-quantum) encryption algorithms, and more.
