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…

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…
