Learn Quantum Computing with Python and Q#

10 Solving chemistry problems with quantum computers

This chapter covers

• Solving chemistry simulations with quantum computers
• Implementing the Exp operation and the Trotter–Suzuki method
• Creating programs for phase estimation, decomposition, and so on

In chapter 9, we used a number of new Q# features like user-defined types (UDTs) and running programs from Python hosts to help us write a quantum program that could estimate phases. As we will see in this chapter, phase estimation is commonly used in quantum algorithms to build up larger and more complex programs. In this chapter, we’ll look at our first practical application area: chemistry.
