The book presents basic concepts of Quantum Mechanics to the undergraduate and postgraduate students at various colleges and universities. Starting from the preliminary ideas related to quantum mechanics, a systematic and logical approach has been used in the subsequent chapters, together with the inclusion of modern concepts such as field quantization, Schrödingers cat problem, qubits and quantum computing. The approach is conceptual and pedagogical and stress is given on using the Dirac notations.
