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…
When Mei-Gu Guan's 1960 Postmen Get Empowered with Bell's 1964 Nonlocal Correlations, or, Nonlocal Advantage in Vehicle Routing Problem
Abhishek Banerjee, Pratapaditya Bej, Amit Mukherjee +3
Vehicle routing problems, a comprehensive problem category originated from the seminal Chinese Postman Problem (first investigated by Chinese mathematician Mei-Gu Guan), entail str…
Overcoming Traditional No-Go Theorems: Quantum Advantage in Multiple Access Channels
Ananya Chakraborty, Sahil Gopalkrishna Naik, Edwin Peter Lobo +5
Extension of point-to-point communication model to the realm of multi-node configurations finds a plethora of applications in internet and telecommunication networks. Here, we esta…
