Stochastic Analysis of Entanglement-assisted Quantum Communication Channels
Karim S. Elsayed, Olga Izyumtseva, Wasiur R. KhudaBukhsh +1
We present a queueing model for a quantum communication network consisting of a primary queue and a service queue in which Bell pairs are formed and stored. The Bell pairs are inhe…

Balancing Quantum Memories in Asymmetric Repeaters for High-Fidelity Entanglement Distribution
Karim S. Elsayed, Amr Rizk
At the core of the quantum Internet lie quantum repeaters that enable remote end-to-end entanglement generation. Fundamentally, the entanglement generation rate and fidelity of qua…

Utility-driven Optimization of TTL Cache Hierarchies under Network Delays
Karim S. Elsayed, Fabien Geyer, Amr Rizk
We optimize hierarchies of Time-to-Live (TTL) caches under random network delays. A TTL cache assigns individual eviction timers to cached objects that are usually refreshed upon a…
