Spanning-Tree-Packing Protocol for Conference Key Propagation in Quantum Networks

We consider a network of users connected by pairwise quantum key distribution QKD links. Using these pairwise secret keys and public classical communication, the users want to generate a common conference secret key at the maximal rate. We propose an algorithm based on spanning tree packing a kno...

Towards a Global Quantum Internet: a Review of Challenges Facing Aerial Quantum Networks

Quantum networks use principles of quantum physics to create secure communication networks. Moving these networks off the ground using drones, balloons, or satellites could help increase the scalability of these networks. This article reviews how such aerial links work, what makes them difficult ...
