Secure Quantum Key Distribution
read the original abstract
Secure communication plays a crucial role in the Internet Age. Quantum mechanics may revolutionise cryptography as we know it today. In this Review Article, we introduce the motivation and the current state of the art of research in quantum cryptography. In particular, we discuss the present security model together with its assumptions, strengths and weaknesses. After a brief introduction to recent experimental progress and challenges, we survey the latest developments in quantum hacking and counter-measures against it.

Entanglement percolation in random quantum networks
In quantum networks with randomly distributed initial entanglement, classical entanglement percolation depends only on the average value while quantum protocols degrade with increasing distribution width.
