Overview of this book

Dancing with Python helps you learn Python and quantum computing in a practical way. It will help you explore how to work with numbers, strings, collections, iterators, and files. The book goes beyond functions and classes and teaches you to use Python and Qiskit to create gates and circuits for classical and quantum computing. Learn how quantum extends traditional techniques using the Grover Search Algorithm and the code that implements it. Dive into some advanced and widely used applications of Python and revisit strings with more sophisticated tools, such as regular expressions and basic natural language processing (NLP). The final chapters introduce you to data analysis, visualizations, and supervised and unsupervised machine learning. By the end of the book, you will be proficient in programming the latest and most powerful quantum computers, the Pythonic way.

5.5 Complex numbers

The complex numbers extend the real numbers by adding the square root of –1. Mathematicians typically call this square root i, but people in fields like electrical engineering use j. Python uses j. I strongly disagree with this choice, but it is part of the language now. As you work with Python and read technical documents, you may need to translate mentally back and forth between i and j.

The cmath module provides many functions and methods for working with complex numbers. These include complex versions of inf, nan, e, pi, tau, and the trigonometric, hyperbolic, exponential, and logarithmic functions.

5.5.1 Creating complex numbers

For a and b real numbers, a complex number z looks like a + b i. The real part Re(z) of z is a, and the imaginary part ...
