Quantum Communication, Quantum Networks and Quantum Sensing: An Applied Approach, Second Edition, is a self-contained and up-to date introduction to quantum communication, quantum error-correction, quantum networks, and quantum sensing. It provides everything an engineer or computer scientist needs in one tutorial-based introduction to understand and implement quantum-level circuits and modules for quantum communication and networking, quantum sensing, and quantum error correction. This text is suitable for engineers, computer scientists, optical engineers, physicists and mathematicians who want a non-theoretical and practical introduction to quantum communications, quantum networks and quantum sensing. - Provides a clear and easy to understand introduction to the principles that do not require knowledge of quantum mechanics - Gives an in-depth explanation of designing quantum error correction circuits, quantum communication systems, quantum networks, and quantum sensing systems - Shows how to design information processing circuits, stabilizer codes, CCS codes, entanglement-assisted quantum error correction codes - Gives an introduction to quantum machine learning
