This book is about quantum computing and quantum algorithms. The book starts with a chapter introducing the basic rules of quantum mechanics and how they can be used to build quantum circuits and perform computations.
Further, Grover's algorithm is presented for unstructured search discussing its consequences and applications.
Next, important techniques are discussed such as Quantum Fourier Transform and quantum phase estimation. Finally, Shor's algorithm for integer factorization is explained.
At last, quantum walks are explained in detail covering both the discrete and continuous time models,and applications of this techniques are described for the design and analyses of quantum algorithms.

Modern introduction to quantum computing, quantum circuits and quantum algorithms This book is self-contained and is well suited to readers from different backgrounds Includes the following topics: Grover's algorithm with proof of correctness and complexity as well as applications; Shor's algorithm for integer factorization with a complete description of quantum Fourier transform and phase estimation; quantum walks in both discrete and continuous time, with emphasis on modern quantum algorithms
