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 resources 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
solution 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
& communications and a wealth of essential, practical
information.
