This book provides a concise introduction to quantum information and quantum science. The author discusses in language accessible to a broad audience, the why and how, as well as implementation technologies. The discussion includes coverage of general computing (e.g., Turing ideas) for comparison, and ideas like entropy and minimum dissipation. Topics such as quantum communications and quantum sensing enhance the discussion of quantum computing. In addition, the manner in which entanglement is used in each of these sub-fields is addressed with applications and, for example, a discussion of the quantum Fourier transform.

Addresses the science of quantum computing, quantum communications, and quantum sensing Covers various approaches currently being used for quantum computing Discusses concisely the science of current approaches to the technology of qubits
