Quantum Resource Theories beyond Convexity
Roberto Salazar, Jakub Czartowski, Ricard Ravell RodrÃguez +3
A class of quantum resource theories, based on non-convex star-shape sets, presented in this work captures the key quantum properties that cannot be studied by standard convex theo…
The operational no-signalling constraints and their implications
MichaÅ Eckstein, Tomasz Miller, Ryszard Horodecki +2
The study of quantum correlations within relativistic spacetimes, and the consequences of relativistic causality on information processing using such correlations, has gained much…
Unbounded Quantum Advantage in Communication with Minimal Input Scaling
Sumit Rout, Nitica Sakharwade, Some Sankar Bhattacharya +2
In communication complexity-like problems, previous studies have shown either an exponential quantum advantage or an unbounded quantum advantage with an exponentially large input s…
