Superadditivity of Zero-Error Capacity in Noisy Classical and Perfect Quantum Channel Pairs
Ambuj, Anushko Chattopadhyay, Kunika Agarwal +2
We demonstrate superadditivity of one-shot zero-error classical capacity in an asymmetric communication setting where a noisy classical channel is used in parallel with a perfect q…

Zero-Error Nash Equilibrium: Harnessing Nonlocal Correlation in Incomplete Information Games
Ambuj, Tushar, Siddharth R. Pandey +4
Claude Shannon's zero-error communication paradigm reshaped our understanding of fault-tolerant information transfer. Here, we adapt this notion into game theory with incomplete in…
