Book Description
Quantum computing is an exciting subject that offers hope to solve the world’s most complex problems at a quicker pace. It is being used quite widely in different spheres of technology, including cybersecurity, finance, and many more, but its concepts, such as superposition, are often misunderstood because engineers may not know the math to understand them. This book will teach the requisite math concepts in an intuitive way and connect them to principles in quantum computing.
Starting with the most basic of concepts, 2D vectors that are just line segments in space, you’ll move on to tackle matrix multiplication using an instinctive method. Linearity is the major theme throughout the book and since quantum mechanics is a linear theory, you’ll see how they go hand in hand. As you advance, you’ll understand intrinsically what a vector is and how to transform vectors with matrices and operators. You’ll also see how complex numbers make their voices heard and understand the probability behind it all.
It’s all here, in writing you can understand. This is not a stuffy math book with definitions, axioms, theorems, and so on. This book meets you where you’re at and guides you to where you need to be for quantum computing. Already know some of this stuff? No problem! The book is componentized, so you can learn just the parts you want. And with tons of exercises and their answers, you’ll get all the practice you need.
What you will learn
Operate on vectors (qubits) with matrices (gates)
Define linear combinations and linear independence
Understand vector spaces and their basis sets
Rotate, reflect, and project vectors with matrices
Realize the connection between complex numbers and the Bloch sphere
Determine whether a matrix is invertible and find its eigenvalues
Probabilistically determine the measurement of a qubit
Tie it all together with bra-ket notation
Who this book is for
If you want to learn quantum computing but are unsure of the math involved, this book is for you. If you’ve taken high school math, you’ll easily understand the topics covered. And even if you haven’t, the book will give you a refresher on topics such as trigonometry, matrices, and vectors. This book will help you gain the confidence to fully understand quantum computation without losing you in the process!

I am interested in quantum computing for years but frustrated by the math. Finally found a book that enables me to learn essential mathematics for understanding quantum computing. Very grateful for the author to write this book.
The book is a student-friendly introduction to learning the basics of superposition, matrix operations, quantum gates, sets, functions, vector space, subspace, linear independence transformation inspired by Euclid, complex numbers, Eigenvectors, Tensor products, etc. The last chapter introduces advanced topics such as Gram-Schmidt, Spectral decomposition, Singular value decomposition, Polar decomposition, etc. Each chapter of the book contains exercise questions with solutions. The mathematical concepts are explained in a beginner-friendly manner, and anyone can understand them.
The drawbacks include the size of figures 1.6, 1.7, 1.8, 5.12, 5.13, etc., being too large and occupying almost complete pages, which wastes resources. In appendix 2 the summation symbol on page 202 occupies one entire page. To understand the practical implementation of quantum algorithms, I would recommend other Packt books written by Robert Loredo and Robert S. Sutor.
Very useful book. Topics are presented simply and practically. Also looks great on my book shelf- I look like a quantum genius!
This book is very well written and has great figures and examples. A must-read and a good reference book on quantum mathematics.
I have read about one-fourth and presentation is pretty clear. Note that I am a novice.
