No Absolute Hierarchy of Quantum Complementarity
Kunika Agarwal, Sahil Gopalkrishna Naik, Ananya Chakraborty +4
Bohr's principle of complementarity, prohibiting simultaneous access to certain physical properties within a single experimental arrangement, is considered to be a defining feature…
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…
Gottesman-Knill Limit on One-way Communication Complexity: Tracing the Quantum Advantage down to Magic Resources
Snehasish Roy Chowdhury, Sahil Gopalkrishna Naik, Ananya Chakraborty +5
Quantum systems are known to offer advantages over their classical counterpart in communication complexity protocols, where the aim is to minimize the amount of information exchang…
Quantum Incompatibility in Parallel vs Antiparallel Spins
Ram Krishna Patra, Kunika Agarwal, Biswajit Paul +3
We explore the joint measurability of incompatible qubit observables on ensembles of parallel and antiparallel spin-1/2 pairs. In parallel configuration, both spins are prepared in…
Nonlocality-Assisted Enhancement of Error-Free Communication in Noisy Classical Channels
Kunika Agarwal, Sahil Gopalkrishna Naik, Ananya Chakraborty +5
The zero-error capacity of a noisy classical channel quantifies its ability to transmit information with absolute certainty, i.e., without any error. Unlike Shannon's standard chan…
Scalable & Noise-Robust Communication Advantage of Multipartite Quantum Entanglement
Ananya Chakraborty, Ram Krishna Patra, Kunika Agarwal +4
Distributed computing, involving multiple servers collaborating on designated computations, faces a critical challenge in optimizing inter-server communication -- an issue central…
