The Capacity Region of the Broadcast Channel with Non-Signaling Assistance
Yuhang Yao, Syed A. Jafar
The paper determines the exact set of achievable communication rates for a K‑user discrete memoryless broadcast channel when the transmitter and all receivers can use non‑signaling…
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%),…
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…
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_{…
