At present scenario is study of Quantum Computing is an unavoidable aspect of today?s Artificial Intelligent world. Quantum computing is still in its early stages, often referred to as the ?Noisy Intermediate-Scale Quantum? (NISQ) era. Yet, rapid advancements suggest that practical, scalable quantum computers may become a reality sooner than expected. Still, the concept and practical application of Quantum Computing rises many interesting questions and offering a radically new approach to computation. The text book ?Quantum computing: Beginner?s Guide? serves as an introduction to the foundational principles, potential applications, and current state of quantum computing. It is intended for readers with a basic understanding of linear algebra and classical computing, but it also aims to be accessible to curious learners from a variety of backgrounds.
