Introduction

Q uantum computing is rapidly spreading among tech communities and almost every business professional or IT expert is asking the question as to what this is and how can I get started. I encountered this many times and I started asking the question to myself on how can I compile a complete knowledge base for quantum computing? The goal was really to have all the important topics in one single book for a business or IT professional to get started with quantum computing.

For me quantum computing began with post-grad education, so it was much easier to understand the basic concepts such as superposition and entanglement as the foundation of quantum computing. As I have been working with cloud computing and application development communities for many years, I realized that this was not as easy for other members of this community. There are many IT and App developers with no previous experience in quantum mechanics let along quantum computing. This makes it much more difficult to expand the quantum computing community because the developers and engineers have an initial fear in getting into this field. But we should know that this field is expanding very fast and there are already significant amounts of budget invested on quantum computing.

Quantum Computing Market

Quantum computing market is already estimates as multi-billion dollar and it is going up faster than any technology in the past. Based on some market forecasts just in the US the expected market for quantum computing is expected to surpass 5 billion USD in the next 3-5 years and global market is already more than that. What I get from these numbers is that quantum computing is real, and it is here to stay AND change everything with it. So, the best approach here is to start learning and once you get started you will see that it is easier than you had originally thought.

Another encouragement for learning quantum computing is the existing job market for quantum experts. Based on some benchmarks already existing open roles related to quantum computing exceeds 500,000 globally and it is expected to rise even more. These jobs although deal with various aspects of quantum computing almost all of them require some basic knowledge of the technology even the ones related to sales and marketing.

So how do we start? This book. Really, this book is an excellent choice to learn the basics and lay the foundation for your quantum acumen with good depth in quantum algorithms. After reading this book if you follow the labs and use the source codes provided you will become a quantum developer qualified for many of the open jobs.

One question I received from reviewers of this book was why "Quantum-Native", so let us start with addressing that question first.

Quantum-Native Definition

The phrase quantum-native refers to a set of solutions and application that begin with looking at the problem using a quantum approach. In many cases, quantum computing approaches look at classical use cases and try to implement these with quantum computing. This approach fails to harness the complete potential hidden in the quantum gates and quantum algorithms and APIs and all the stack that form an application. In this book, I have presented a proposed software architecture for such quantum-native applications, and you can see that this approach natively looks at the quantum approach without much influence from the classical world. It is important to keep this mindset while reading this book that quantum computing can do a lot and it can do things that classical computing will never be able to perform. Another book in this series in quantum-native machine learning and there you will see such facets of quantum computing. Thus, it is important to keep in mind that we look at quantum computing as a complete set of solution to encompasses over the entire software stack and not only a portion of that which is computation. I define this approach is quantum-native and the application developed based on this approach would be a quantum-native application. application developed based on this approach would be a quantum-native application.

Preface

T his book provides a comprehensive and complete overview on quantum computing and developing quantum-native applications. As you will discover this is a very broad spectrum to cover and according to my knowledge there has not been such an effort done to date which makes this book unique in many ways.
