Strong -valued contextuality: ruling out discrete nondeterministic alternatives to quantum theory
Ravishankar Ramanathan
The paper builds finite measurement setups that exclude noncontextual hidden‑variable models with outcome probabilities from any finite set, extending the Kochen‑Specker theorem an…
When Quantum Nonlocality Does Not Play Dice
Ravishankar Ramanathan, Yuan Liu, Stefano Pironio
The authors demonstrate that certain Bell inequalities can be maximally violated by quantum correlations yet certify no randomness for any fixed input pair, and they construct expl…
On-Chip Quantum Randomness Amplification
Lang Li, Yutian Wu, Giulio Chiribella +1
Randomness amplification, the task of extracting uniform private bits from biased seeds that may be partly known by a malicious third party, is of central importance in cryptograph…
Self-testing with untrusted random number generators
Moisés Bermejo Morán, Ravishankar Ramanathan
Self-testing--the attractive possibility to infer the underlying physics of a quantum device in a black-box scenario--has gained increased traction in recent years, with applicatio…
Quantum Nonlocality and Device-Independent Randomness Robust to Relaxations of Bell Assumptions
Ravishankar Ramanathan, Yuan Liu
The question of certifying quantum nonlocality under a relaxation of the assumptions in the Bell theorem has gained traction, with potential for device-independent applications und…
No Bound Randomness in Quantum Nonlocality
Ravishankar Ramanathan, Yuan Liu, Yutian Wu +1
Recently it has been found that there exist maximally nonlocal quantum correlations that fail to certify randomness for any fixed input pair, rendering them useless for device-inde…
