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. Can you list all the simulators found in the Aer library?
  2. How many total simulators are there altogether in Qiskit? (Hint: This includes Basic Aer, Aer, and IBM Quantum Provider.)
  3. Create a QSphere representation of a qubit on the negative y axis, creating the state , using only a single Hadamard gate along with the phase gates.
  4. What must the initialized probability value of a circuit be in order to be valid?
  5. Can you use the QSphere to visualize both the phase and probability information of a qubit?
  6. How would you apply a noise function to qubits 2, 3, and 4 of a 5-qubit system?
  7. What would happen if you set the depolarization error values close to 1?
  8. If you applied a readout error equally to all qubits, what results would you expect, and why?
