Degrees of Freedom of Over-the-Air Computation over a MIMO Gaussian Network with Two Transmitters and Two Receivers
Yong Dong, Hua Sun, Syed A. Jafar
The fundamental limits of over-the-air computation (AirComp) are explored in a two-transmitter, two-receiver MIMO Gaussian network, where both receivers demand the same aggregation…
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…
On the Generic Capacity of -User Symmetric Linear Computation Broadcast
Yuhang Yao, Syed A. Jafar
Linear computation broadcast (LCBC) refers to a setting with dimensional data stored at a central server, where users, each with some prior linear side-information, wish to…
