- We prove mathematically and provide extensive simulation evidence that certain quantum networks have an anti-congestion core: a small set of nodes that see hardly any network traffic, while all other nodes are completely connected. A seminal experimental and theoretical result for classical networks, especially the Internet, is that they do have a congestion core, a small set of nodes that see most traffic/congestion, as such networks are Gromov hyperbolic. We show quantum networks can go beyond this limitation, despite also being hyperbolic. This provides a quantum routing concept and suggests a Quantum Internet has bandwidth advantages over classical networks.
