Synopses & Reviews
Quantum computers will revolutionize the way telecommunications networks function.Quantum computing holds the promise of solving problems that would be intractable with conventional computers, by implementing principles from quantum physics in the development of computer hardware, software and communications equipment.
Quantum-assisted computing will be the first step towards full quantum systems and will cause immense disruption of our traditional networks. The world’s biggest manufacturers are investing large amounts of resource to develop crucial quantum-assisted circuits and devices.
Quantum Computing and Communications:
- Gives an overview of basic quantum computing algorithms and their enhanced versions such as efficient database searching, counting and phase estimation.
- Introduces quantum-assisted solutions for telecom problems including multi-user detection in mobile systems, routing in IP based networks, and secure ciphering key distribution.
- Includes an accompanying website featuring exercises (with solutions manual) and sample algorithms from the classical telecom world, corresponding quantum-based solutions, bridging the gap between pure theory and engineering practice.
This book provides telecommunications engineers, as well as graduate students and researchers in the fields of computer science and telecommunications, with a wide overview of quantum computing and communications and a wealth of essential, practical information.
Synopsis
Quantum computing devices can be classified according to the environment they work in: Quantum assisted equipment solves problems in traditional systems, such as signal demodulation in 4G mobile systems, or increases the efficiency of a network-planning tool. Quantum based devices operate in a quantum environment e.g. in quantum channels. Both topics bear huge potential for the future of telecoms engineering. Transistors of integrated circuits are already built to atomic scale, i.e. quantum effects must be considered.
"Quantum Computing for Communications: Uniquely discusses quantum computing from an engineering point of view. Comprehensively introduces quantum computing, quantum algorithms, quantum assisted solutions for telecommunication problems, and quantum based communications. Provides an overview of the properties of a typical quantum channel and the quantum counterparts of the classical lower layer techniques such as source compression, channel coding, multiple access control, etc. Introduces several computationally hard telecommunications problems (multi-user detection in wireless system, network planning, digital signature, etc.) and their quantum-assisted solutions.
The accompanying website includes exercises (with solution manual) and sample algorithms from the classical telecom world and corresponding quantum based solutions, building a bridge between pure theory and everyday engineering practice.
