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…

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…

On the Impact of Network Delays on Time-to-Live Caching

Karim Elsayed, Amr Rizk

We consider Time-to-Live (TTL) caches that tag every object in cache with a specific (and possibly renewable) expiration time. State-of-the-art models for TTL caches assume zero ob…
