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…
On the Capacity Region of Individual Key Rates in Vector Linear Secure Aggregation
Lei Hu, Sennur Ulukus
We provide new insights into an open problem recently posed by Yuan-Sun [ISIT 2025], concerning the minimum individual key rate required in the vector linear secure aggregation pro…
Entanglement-Assisted Coding for Arbitrary Linear Computations Over a Quantum MAC
Lei Hu, Mohamed Nomeir, Alptug Aytekin +3
We study a linear computation problem over a quantum multiple access channel (LC-QMAC), where servers share an entangled state and separately store classical data streams $W_1,…
