Overview of this book

Navigate the quantum computing spectrum with this book, bridging the gap between abstract, math-heavy texts and math-avoidant beginner guides. Unlike intermediate-level books that often leave gaps in comprehension, this all-encompassing guide offers the missing links you need to truly understand the subject. Balancing intuition and rigor, this book empowers you to become a master of quantum algorithms. No longer confined to canned examples, you'll acquire the skills necessary to craft your own quantum code. Quantum Computing Algorithms is organized into four sections to build your expertise progressively. The first section lays the foundation with essential quantum concepts, ensuring that you grasp qubits, their representation, and their transformations. Moving to quantum algorithms, the second section focuses on pivotal algorithms — specifically, quantum key distribution and teleportation. The third section demonstrates the transformative power of algorithms that outpace classical computation and makes way for the fourth section, helping you to expand your horizons by exploring alternative quantum computing models. By the end of this book, quantum algorithms will cease to be mystifying as you make this knowledge your asset and enter a new era of computation, where you have the power to shape the code of reality.

What this book covers

Introduction to Quantum Computing, provides an overview of quantum computing and defines some important terms.

Chapter 1, New Ways to Think about Bits, shows how matrix operations can be used to describe logic gates in classical computing. This chapter also introduces Jupyter notebooks as an environment for writing and running computer programs.

Chapter 2, What Is a Qubit?, describes superposition – a strange characteristic of quantum entities that’s vastly different from the behavior of classical bits. This chapter also introduces Qiskit – IBM’s quantum computing software development kit.

Chapter 3, Math for Qubits and Quantum Gates, provides a way of using matrices to represent qubits’ states.

Chapter 4, Qubit Conspiracy Theories, introduces entanglement using multi-qubit gates.

Chapter 5, A Fanciful Tale about Cryptography, shows how quantum superposition can be used to ensure secure communication between two parties.

Chapter 6, Quantum Networking and Teleportation, describes a way in which one qubit’s state can be transferred to another qubit. This is an essential element in the transmission of quantum information from one place to another.

Chapter 7, Deutsch’s Algorithm, explains how a quantum computer can use superposition and entanglement to solve a simple problem in one step.

Chapter 8, Grover’s Algorithm, shows how a quantum computer can search through a list without examining each of the list’s elements.

Chapter 9, Shor’s Algorithm, describes the way quantum computers will be able to break some of our commonly used cryptographic schemes.

Chapter 10, Some Other Directions for Quantum Computing, describes some alternative approaches to quantum computing.
