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…
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…
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…
Collaborative Optimization of the Age of Information under Partial Observability
Anam Tahir, Kai Cui, Bastian Alt +2
The significance of the freshness of sensor and control data at the receiver side, often referred to as Age of Information (AoI), is fundamentally constrained by contention for lim…
On the Fidelity Distribution of Link-level Entanglements under Purification
Karim Elsayed, Wasiur R. KhudaBukhsh, Amr Rizk
Quantum entanglement is the key to quantum communications over considerable distances. The first step for entanglement distribution among quantum communication nodes is to generate…
