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…
Stronger Nonlocality in GHZ States: A Step Beyond the Conventional GHZ Paradox
Ananya Chakraborty, Kunika Agarwal, Sahil Gopalkrishna Naik +1
The Greenberger-Horne-Zeilinger (GHZ) paradox, involving quantum systems with three or more subsystems, offers an 'all-vs-nothing' test of quantum nonlocality. Unlike Bell tests fo…
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…
Harnessing Causal Indefiniteness for Accessing Locally Inaccessible Data
Sahil Gopalkrishna Naik, Samrat Sen, Ram Krishna Patra +4
Recent studies suggest that physical theories can exhibit indefinite causal structures, where the causal order of events is fundamentally undefined yet logically consistent. Beyond…
Ergodiscord: An Operational and Distinct Notion of Quantumness of Correlations
Mir Alimuddin, Snehasish Roy Chowdhury, Ram Krishna Patra +4
Nonclassicality in composite quantum systems depicts several puzzling manifestations, with Einstein-Podolsky-Rosen entanglement, Schrödinger steering, and Bell nonlocality being th…
Asymptotic Birkhoff-Violation in Operational Theories: Thermodynamic Implications and Information Processing
Ananya Chakraborty, Sahil Gopalkrishna Naik, Samrat Sen +4
In accordance with the entropy principle of thermodynamics, under spontaneous evolutions, physical systems always evolve towards states with equal or greater randomness. But, where…
Quantum Advantage: A Single Qubit's Experimental Edge in Classical Data Storage
Chen Ding, Edwin Peter Lobo, Mir Alimuddin +5
We implement an experiment on a photonic quantum processor establishing efficacy of the elementary quantum system in classical information storage. The advantage is established by…
