No-Disturbance-without-Uncertainty generates the Quantum set in the simplest Bell scenario
Ravishankar Ramanathan
Characterizing the set of quantum nonlocal correlations through information-theoretic constraints is a central problem in quantum foundations. We show that the convex hull of no-si…
Strong -valued contextuality: ruling out discrete nondeterministic alternatives to quantum theory
Ravishankar Ramanathan
Gleason's theorem identifies the Born rule via non-contextuality over an infinite continuous lattice of projectors, while its corollary the Kochen-Specker (KS) theorem rules out th…
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…
