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…
Finite Device-Independent Extraction of a Block Min-Entropy Source against Quantum Adversaries
Ravishankar Ramanathan
The extraction of randomness from weakly random seeds is a problem of central importance with multiple applications. In the device-independent setting, this problem of quantum rand…
Optimal Measurement Structures for Contextuality Applications
Yuan Liu, Ravishankar Ramanathan, Karol Horodecki +2
The Kochen-Specker (KS) theorem is a corner-stone result in the foundations of quantum mechanics describing the fundamental difference between quantum theory and classical non-cont…
The rank of contextuality
Karol Horodecki, Jingfang Zhou, Maciej Stankiewicz +6
Quantum contextuality is one of the most recognized resources in quantum communication and computing scenarios. We provide a new quantifier of this resource, the rank of contextual…
Multipartite channel assemblages
Michał Banacki, Ravishankar Ramanathan, Paweł Horodecki
Motivated by the recent studies on post-quantum steering, we generalize the notion of bipartite channel steering by introducing the concept of multipartite no-signaling channel ass…
Tilted Hardy paradoxes for device-independent randomness extraction
Shuai Zhao, Ravishankar Ramanathan, Yuan Liu +1
The device-independent paradigm has had spectacular successes in randomness generation, key distribution and self-testing, however most of these results have been obtained under th…
