Get Smart!  Quantum Networks and Quantum Repeaters: An Illustrated Intro

…In this blogpost, [the authors] explain basic principles and use cases of quantum networks while explaining how a quantum repeater (a key piece of quantum network infrastructure) works…

…[They] start by introducing the basics of quantum bits and entanglement. Next, [they] show how distributed entanglement can generate cryptographic keys for customers…

…[The authors] discuss the current state-of-the-art in entanglement distribution and its shortcoming – limited network range. Finally, [they] discuss how the range limitation of current quantum networks can be overcome with quantum repeaters, devices that can store and perform joint measurements on quantum bits…
