Learn Quantum Computing with Python and IBM Quantum Experience

By: Robert Loredo

Overview of this book

IBM Quantum Experience is a platform that enables developers to learn the basics of quantum computing by allowing them to run experiments on a quantum computing simulator and a real quantum computer. This book will explain the basic principles of quantum mechanics, the principles involved in quantum computing, and the implementation of quantum algorithms and experiments on IBM's quantum processors. You will start working with simple programs that illustrate quantum computing principles and slowly work your way up to more complex programs and algorithms that leverage quantum computing. As you build on your knowledge, you’ll understand the functionality of IBM Quantum Experience and the various resources it offers. Furthermore, you’ll not only learn the differences between the various quantum computers but also the various simulators available. Later, you’ll explore the basics of quantum computing, quantum volume, and a few basic algorithms, all while optimally using the resources available on IBM Quantum Experience. By the end of this book, you'll learn how to build quantum programs on your own and have gained practical quantum computing skills that you can apply to your business.

Appendix A: Resources


  1. Create a circuit that implements Deutsch's algorithm for a constant function and verify your results.
  2. Which algorithm would you use to determine whether an n-bit string is balanced?
  3. Would phase kickback work if the ancilla qubit was not set to the state |1? Explain your answer.
  4. Implement the Bernstein-Vazirani algorithm to find the state |11010.
  5. What would happen if you set the ancilla qubit in either of the algorithms by first placing a Hadamard gate, followed by an X gate? Explain the reason for the results.
  6. Program and create an automated oracle generator for the Bernstein-Vazirani algorithm that randomly generates the secret state. Can you determine the value by just running the circuit and reviewing the results?
