Chapter 7

Quantum Entanglement and QKD

Chapter Objectives

After reading this chapter and completing the review questions, you will be able to do the following:

  • Understand quantum entanglement

  • Have a deeper understanding of quantum states

  • Demonstrate a working knowledge of quantum key exchange protocols

Quantum entanglement is a difficult subject to understand conceptually. It is totally counterintuitive, and it took many experiments to verify that it is indeed true. However, it is a critical element of quantum physics, and in this chapter we will explore that topic. A related topic is quantum key distribution (QKD). In this chapter, you will learn the basics of QKD as well as actual implementations of QKD.
