The Capacity Region of the Multiple Access Channel with Non-Signaling Assistance
Yuhang Yao, Syed A. Jafar
The capacity region of the -sender discrete memoryless multiple access channel (MAC) is fully characterized when non-signaling (NS) assistance is available to all transmitte…
Wireless Linear Computation Broadcast
Shuo Tan, Syed A. Jafar
A linear computation broadcast (LCBC) problem comprises users (receivers) and a transmitter. The users wish to compute various (vector) linear functions of a common dataset, an…
The Capacity Region of the Broadcast Channel with Non-Signaling Assistance
Yuhang Yao, Syed A. Jafar
The capacity region of the -user discrete memoryless broadcast channel is fully characterized when non-signaling (NS) assistance is available to the transmitter and all rece…
Unlocking Exponential and Unbounded Robust Gains in Shannon Capacity of Classical Multiple Access Channels with Causal CSIT via Quantum Entanglement Assistance
Yuhang Yao, Syed A. Jafar
Quantum entanglement assistance is known to improve the Shannon capacity of classical communication networks but the largest gains noted thus far are rather modest (less than 6%),…
Non-signaling Assisted Capacity of a Classical Channel with Causal CSIT
Yuhang Yao, Syed A. Jafar
The non-signaling (NS) assisted capacity of a classical discrete memoryless channel with causal channel state information at the transmitter (CSIT) is shown to be $C^{NS,ca}=\max_{…
On the Capacity of Distributed Quantum Storage
Hua Sun, Syed A. Jafar
A distributed quantum storage code maps a quantum message to N storage nodes, of arbitrary specified sizes, such that the stored message is robust to an arbitrary specified set of…
