Blind Interference Alignment for MapReduce: Exploiting Side-information with Reconfigurable Antennas
Yuxiang Lu, Syed A. Jafar
In order to explore how blind interference alignment (BIA) schemes may take advantage of side-information in computation tasks, we study the degrees of freedom (DoF) of a user…
Quantum -Secure -Private Information Retrieval From MDS Coded Storage With Unresponsive and Byzantine Servers
Yuxiang Lu, Syed A. Jafar
A communication-efficient protocol is introduced over a many-to-one quantum network for Q-E-B-MDS-X-TPIR, i.e., quantum private information retrieval with MDS--secure storage an…
On the Capacity of Secure -user Product Computation over a Quantum MAC
Yuxiang Lu, Yuhang Yao, Syed A. Jafar
Inspired by recent work by Christensen and Popovski on secure -user product computation for finite-fields of prime-order over a quantum multiple access channel, the generalizati…
Quantum Cross Subspace Alignment Codes via the -sum Box Abstraction
Yuxiang Lu, Syed Ali Jafar
Cross-subspace alignment (CSA) codes are used in various private information retrieval (PIR) schemes (e.g., with secure storage) and in secure distributed batch matrix multiplicati…
On Single Server Private Information Retrieval with Private Coded Side Information
Yuxiang Lu, Syed Ali Jafar
Motivated by an open problem and a conjecture, this work studies the problem of single server private information retrieval with private coded side information (PIR-PCSI) that was…
