Learn Quantum Computing with Python and Q#

11 Searching with quantum computers

This chapter covers

• Searching unstructured data with a quantum algorithm
• Using the QDK resources estimator to understand the costs of running algorithms
• Reflecting quantum registers about states

In chapter 10, we got to dig into our first application of quantum computing by working with our colleague Marie to help calculate the ground state energy of a hydrogen molecule. To do so, we implemented a Hamiltonian simulation algorithm that used some of the phase-estimation techniques we developed in chapter 9.

In this chapter, we’ll look at another application of quantum computing: searching data. This application area is always a hot topic in high-performance computing areas and shows off another way we can ...
