Dancing with Python

By: Robert S. Sutor

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.

9.1 The software stack

Software runs on hardware, and you use both to build applications and solve problems. This is true whether you are working entirely on a laptop or access computing resources on the cloud. Software is not monolithic. It begins with a layer very close to the hardware. On top of that, we implement abstractions and higher-level features to make it easier to code and develop solutions.

Classical and quantum software stack
Figure 9.1: Classical and quantum software stack

We have gates and circuits within the hardware and the software layers. These are the most primitive operations, and we make compositions of them into useful processes.

Assembly languages allow us to code gates into custom circuits. They let us control the underlying hardware and, in the classical case, access and use system memory. OpenQASM3 is an example of a quantum computing assembly language developed...
