  The second quantum revolution has been picking up momentum over the last
decade. Quantum technologies are starting to attract more attention from
governments, private companies, investors, and public. The ability to control
individual quantum systems for the purpose of information processing and
communication is no longer a theoretical dream, but is steadily becoming
routine in laboratories and startups around the world. With this comes the need
to educate the future generation of quantum engineers. This textbook is a
companion to our video lectures on Overview of Quantum Communications from the
Q-Leap Education project known as Quantum Academy of Science and Technology. It
is a gentle introduction to quantum networks, and is suitable for use as a
textbook for undergraduate students of diverse background. No prior knowledge
of quantum physics or quantum information is assumed. Exercises are included in
each chapter.
