Quantum Computing in Action

5 Entanglement

This chapter covers

• The analogy between flipping a coin and getting a random number
• Relating flipping coins and probability vectors
• The physical concept of quantum entanglement
• Using quantum entanglement to create connected random numbers
• Understanding how to use superposition and entanglement in Java applications

In the previous chapter, we introduced and explained the concept of superposition. This concept does not exist in classical computing, and it is one of the reasons quantum computing is fundamentally different from classical computing. Nevertheless, we managed to describe superposition in such a way that a Java programmer can use it in their code. In this chapter, we introduce quantum entanglement, a concept that is ...
