Storage-Rate Trade-off in A-XPIR
Mohamed Nomeir, Sennur Ulukus
We consider the storage problem in an asymmetric -secure private information retrieval (A-XPIR) setting. The A-XPIR setting considers the -secure PIR problem (XPIR) when a gi…
Simultaneously Minimizing Storage and Bandwidth Under Exact Repair With Quantum Entanglement
Lei Hu, Mohamed Nomeir, Alptug Aytekin +1
We study exact-regenerating codes for entanglement-assisted distributed storage systems. Consider an distributed system that stores a file of cla…
Private Information Retrieval With Arbitrary Privacy Requirements for Graph-Based Storage
Mohamed Nomeir, Shreya Meel, Sennur Ulukus
We reformulate the definition of privacy in the private information retrieval (PIR) problem to accommodate flexible privacy requirements. We focus on graph-replicated PIR, with a g…
Local Private Information Retrieval: A New Privacy Perspective for Graph-Based Replicated Systems
Shreya Meel, Mohamed Nomeir, Sennur Ulukus
We rethink the definition of privacy in multi-server, graph-replicated private information retrieval (PIR) systems, and introduce a novel setting where the user's privacy is govern…
Convergence Properties of Good Quantum Codes for Classical Communication
Alptug Aytekin, Mohamed Nomeir, Lei Hu +1
An important part of the information theory folklore had been about the output statistics of codes that achieve the capacity and how the empirical distributions compare to the outp…
Breaking the Storage-Bandwidth Tradeoff in Distributed Storage with Quantum Entanglement
Lei Hu, Mohamed Nomeir, Alptug Aytekin +1
This work investigates the use of quantum resources in distributed storage systems. Consider an distributed storage system in which a file is stored across nodes such…
