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…
Optimal Average Success Probabilities of Binary and Quantum Random Access Codes
Shuo Tan, Syed A. Jafar
A binary quantum random access code (QRAC) compresses an -bit classical string into an -qubit quantum state, from which a decoder attempts to recover a randomly selec…
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%),…
Quantum Entanglement Assistance Improves the Capacity and Activates the Zero-Error Capacity of Classical Channels with Causal CSIT
Yuhang Yao, Syed A. Jafar
For classical point-to-point channels, it has been shown by Bennett et al. that quantum entanglement assistance cannot improve their capacity, and by Cubitt et al. that entanglemen…
Space-sharing and Singleton Bounds for Entanglement-assisted Classical Coding
Yuhang Yao, Tushita Prasad, Markus Grassl +2
Recent work has noted that a space-sharing argument proves the tightness of the entropic quantum Singleton bounds, which was left open in the literature for various settings involv…
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…
On the Capacity of Erasure-prone Quantum Storage with Erasure-prone Entanglement Assistance
Hua Sun, Syed A. Jafar
A quantum message is encoded into storage nodes (quantum systems ) with assistance from maximally entangled bi-partite quantum systems $A_1B_1, \dots, A_{N_…
Virtual Signaling of CSIT via Non-Signaling Assistance
Yuhang Yao, Syed A. Jafar
Non-signaling correlations, which (strictly) include quantum correlations, provide a tractable path to explore the potential impact of quantum nonlocality on the capacity of classi…
On the Utility of Quantum Entanglement for Joint Communication and Instantaneous Detection
Yuhang Yao, Syed A. Jafar
Entanglement is known to significantly improve the performance (separately) of communication and detection schemes that utilize quantum resources. This work explores the simultaneo…
Can Non-Signaling Assistance Increase the Degrees of Freedom of a Wireless Network?
Yuhang Yao, Syed A. Jafar
An open question posed by Fawzi and Ferme [Transactions on Information Theory 2024], asks whether non-signaling (NS) assistance can increase the capacity of a broadcast channel (BC…
Enhancing K-user Interference Alignment for Discrete Constellations via Learning
Rajesh Mishra, Syed Jafar, Sriram Vishwanath +1
In this paper, we consider a K-user interference channel where interference among the users is neither too strong nor too weak, a scenario that is relatively underexplored in the l…
