Aging effects in multiplexed quantum networks — •Lisa T. Weinbrenner1, Lina Vandré1, Tim Coopmans2, and Otfried Gühne1 — 1Universität Siegen, Germany — 2Universiteit Leiden, Netherlands
Aging is a well known problem which effects humans as well as technical devices. It is described by the effect that the probability for a failure in a given time interval increases with the life time of the biological or technological object. Different types of objects (e.g. humans and technical devices) age according to qualitatively different failure rates. The difference can be understood if these objects are modeled as systems of redundant parts with possibly initial defects [1].
Multiplexed quantum networks are quantum networks with multiple connections between two nodes, i.e., with redundancy in the edges of the network [2]. The functionality of the entire network depends on the functionality of the technical devices used. This leads to the question how the failure rates of the single devices lead to aging effects in the entire network. In this contribution we will apply the theory of aging to the technical devices used in a multiplexed quantum network. Our results rely on the analytical treatment of the underlying stochastic process of failure of the devices, as well as numerical simulations for different network structures.
