Inhaltsangabe

“This isn't just another theoretical quantum computing textbook. It's a hands-on, practical guide that bridges the gap between abstract quantum concepts and real-world applications."- Robert Loredo, former Worldwide Team Leader for IBM’s Quantum Ambassador program.

“If you’re new to quantum computing, have not worked through other textbooks, or want a gentle but comprehensive starting point, this book is an excellent choice."- Alex Khan, VP of Quantum R&D BQP

Key Features

• Understand the theoretical foundations of quantum computing
• Learn how to use the Qiskit framework and how to run quantum algorithms with it
• Discover top quantum algorithms like Grover’s search and Shor’s factoring methods
• Purchase of the print or Kindle book includes a free PDF eBook

Book Description

This book is a from-scratch introduction to quantum computing and its most important foundational algorithms, from simple protocols like Deutsch’s algorithm to powerful ones such as Shor’s factoring algorithm. It provides clear explanations and a hands-on approach, with runnable code for both simulators and real quantum hardware. The book is fully self-contained and assumes no prior experience in quantum computing. Starting with a single qubit, it gradually builds up to algorithms that use superposition and entanglement.

Practical applications are presented throughout, including quantum money that cannot be forged, unbreakable quantum cryptography, and quantum algorithms for searching and factoring that significantly outperform classical approaches. All algorithms are implemented and carefully explained using Qiskit 2.1.

By the end of the book, you will understand how quantum algorithms work, how to write your own quantum programs, and how to run them on simulators and real quantum computers, preparing you to move on to advanced topics such as quantum optimization and quantum artificial intelligence.

What you will learn

• Understand what makes a quantum computer unique
• Mathematically represent the state of multi-qubit systems
• Describe the effects of measurements in quantum computers
• Know how quantum superposition, entanglement, and interference work
• Implement and run any quantum algorithm in Qiskit
• Understand how Shor's and Grover's algorithms work
• Gain familiarity with quantum fault-tolerance and quantum advantage

Learn about quantum information processing with Qiskit through hands-on projects. A foundational resource for STEM professionals, researchers and university students interested in quantum computers and algorithms Key Features: - Understand the theoretical foundations of quantum computing - Learn how to use the Qiskit framework and how to run quantum algorithms with it - Discover top quantum algorithms like Grover's search and Shor's factoring methods - Purchase of the print or Kindle book includes a free PDF eBook Book Description: This book is an introduction, from scratch, to quantum computing and the most important and foundational quantum algorithms-ranging from humble protocols such as Deutsch's algorithm to ones with far-reaching potential, such as Shor's factoring algorithm-offering clear explanations and a hands-on approach with runnable code on simulators and real hardware. The book is self-contained and does not assume any previous experience in quantum computing. Starting with a single qubit, it scales to algorithms using superposition and entanglement. At every step, examples of applications are provided, including how to create quantum money that is impossible to forge, quantum cryptography that cannot be broken, and algorithms for searching and factoring that are much faster than those that regular, non-quantum computers can use. Code for each of these algorithms is provided (and explained in detail) using Qiskit 2.1. After reading this book, you will understand how quantum algorithms work, how to write your own quantum programs, and how to run them on quantum simulators and actual quantum computers. You will also be prepared to take the jump into quantum algorithms for optimization and artificial intelligence, like those presented in our previous book, A Practical Guide to Quantum Machine Learning and Quantum Optimization. What You Will Learn: - Understand what makes a quantum computer unique - Mathematically represent the state of multi-qubit systems - Describe the effects of measurements in quantum computers - Know how quantum superposition, entanglement, and interference work - Implement and run any quantum algorithm in Qiskit - Understand how Shor's and Grover's algorithms work - Gain familiarity with quantum fault-tolerance and quantum advantage Who this book is for: This book would be ideal for university-level students in Computer Science, Mathematics, Physics or other STEM fields taking introductory-level courses on quantum computing. It also suits professionals, researchers and self-learners with a STEM background. Potential readers of our previous book, A Practical Guide to Quantum Machine Learning and Quantum Optimization, will benefit from first building foundational quantum computing skills with this book.
