The impact of quantum computing has been widely recognised in the engineering domain. The age of quantum computing has arrived, and with it comes the ability to easily solve exponential problems. This book is written by me to meet current academic demands. The book is designed to address the most important aspects of the subject of Quantum Computing. The publication of the book "Quantum Computing" is the culmination of numerous years of research and teaching in academia. It is given in a way that is straightforward to comprehend. The undergraduates, and graduate students may all benefit from reading this book. We have given our very best effort to bring you accurate book material. The book explains the fundamentals of this topic in simple, straightforward language. The most efficient approach to go through this book is to grasp the underlying fundamental as well as mathematical concepts. The chapters are meant to stand on their own. This book is not intended to be theoretical; rather, it will serve to familiarise you with the fundamental of quantum computing, like applications, multiple-qubit systems, quantum state transformations, quantum gates and quantum circuits, tools for quantum computing, bell states, quantum Parallelism, quantum Algorithms: Shor’s Algorithm, Grover’s Algorithm, Quantum Hardware and software, Quantum Cryptography and Security, Quantum Error Rates and Quantum Noise, Quantum Fourier Transform, Quantum Machine Learning and so on. The model questions and multiple-choice questions that are provided at the end of the book have been chosen to improve readers' understanding, as well as their performance in exams and key employment. We warmly welcome and would be very appreciative of any comments or recommendations, that will help us enhance the overall quality of the book.
