8 Secure communication using quantum computing
This chapter covers
- Solving the bootstrap problem of secure communication
- Introducing quantum key distribution
- Understanding the BB84 algorithm
- Securely distributing shared keys between two parties
In this chapter, you create a useful quantum application. We show that quantum computing allows you to create a secret key that can be shared between two parties in a very secure way. This quantum key distribution (QKD) is the basis for a number of encryption techniques that are proven to be secure—even the best quantum computer can’t break this security!
8.1 The bootstrap problem
We started chapter 6 by showing how classical networks are used to send classical information from one node (or computer) ...
