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.

  1. Using the Quantum Circuit from the example shown in Figure 12.4, create a custom initialized state using the state_vector parameter.
  2. Construct a Circuit State function from a state vector.
  3. Construct a balanced Oracle and verify it using the Deutsch-Jozsa algorithm.
  4. Implement the Bernstein-Vazirani algorithm to find the secret value, 170. (Hint: use the decimal to binary utility).
  5. How many Oracle functions are there?
  6. Does Aqua also include classical algorithms?
  7. Leveraging the qiskit.aqua.circuits.StateVectorCircuit class, construct a circuit that represents an X gate.
  8. Change the backend on QuantumInstance to a quantum computer backend that is available and rerun any of the quantum algorithms. Describe what differences, if any, you were able to observe.
