Physics Theory Seminar with Junpeng Hou on Virus spread in quantum Internet

With recent advances in quantum communications like long-range quantum key distribution and quantum teleportation, we can realize telecommunication via quantum manners on a large scale. This leads to the rapid development of quantum networks as well as the emerging quantum Internet. In this presentation, I will give an overview of quantum communications, network and graph theory and models of the quantum Internet. I will use photon-link-based quantum networks to discuss how quantum channels bring distinct physical and statistical properties to the quantum Internet. I will also give a brief introduction to epidemiology and show how can we adapt these theories to predict the fate of the quantum Internet under viral infection. I will discuss several models for predicting the epidemic
thresholds of the quantum Internet and show that the quantum Internet is more robust. Finally, I will present a model to characterize the infectious dynamics, which brings more insights into the complex system and cross-validates the predictions of epidemic thresholds.
