Go beyond the basics with this in-depth guide to quantum programming.

Here’s something you already know: quantum computing is a deep subject. Quantum Programming in Depth takes you beyond quantum basics and shows you how to take on practical quantum problem solving and programming using Q# and Qiskit. Author Mariia Mykhailova, a principal quantum applications software developer at PsiQuantum, guides you every step of the way.

In Quantum Programming in Depth you’ll explore:

• Algorithms to solve challenging quantum computing problems

• Writing quantum programs with Q# and Qiskit

• Testing quantum programs with simulators and specialized tools

• Evaluating performance of quantum programs on future fault-tolerant quantum computers

Quantum Programming in Depth shows you how to do quantum computing outside the lab or classroom, presenting problems of quantum programming and demonstrating how they’re solved. You’ll learn to write quantum programs using Qiskit and Q#—and even how to test your quantum code using common testing tools like pytest. You’ll learn to prepare quantum states and implement operations, extract information from quantum states and operations, evaluate classical functions on a quantum computer, solve search problems, and more.

About the Technology

Going from the basic quantum concepts to developing software for quantum computers can be difficult! Algorithms that leverage quantum phenomena require new ways of thinking about computation and new approaches to writing code, testing it, and evaluating its performance. This book bridges the gap between QC theory and quantum programming in practice.

About the Book

Quantum Programming in Depth shows you how to solve quantum computing problems in a programmer-friendly way. The book’s hands-on project-based approach will hone your quantum skills using realistic problems and progressively harder programming challenges. As you read, you’ll design quantum algorithms and explore their performance on future fault-tolerant quantum computers.
