Coherent Control of Channel Dilations Activate Temporal Bell Nonclassicality
H S Karthik, Akshata Shenoy H, A R Usha Devi +1
The temporal Clauser-Horne-Shimony-Holt (CHSH) inequality witnesses the nonclassicality of temporal correlations, but its violation is generally degraded by environmental noise. He…
Neural Information Causality
Jeongho Bang, Marcin PawÅowski
Query-separated computation forces a representation to play an operational role: data are encoded before a query is known, and a later decoder can answer only through the intermedi…
Communication-constrained nonlocal correlations
Lucas Pollyceno, Denis Freudenheim, José Nogueira +3
Identifying the physical grounds distinguishing quantum theory from broader probabilistic frameworks remains an open challenge. Communication-based proposals -- most notably the pr…
High-dimensional detection-loophole-free measurement-device-independent quantum random number generator
Joakim Argillander, Daniel Spegel-Lexne, Martin Clason +4
Certifying random number generators is challenging, especially in security-critical fields like cryptography. Here, we demonstrate a measurement-device-independent quantum random n…
Security of device-independent quantum key distribution via monogamy relations from multipartite information causality
Lucas Pollyceno, Anubhav Chaturvedi, Chithra Raj +2
Beyond the foundational significance, the problem of bounding nonlocal correlations by reasonable physical principles has meaningful practical consequences, particularly for device…
Certifying semi-device-independent security via wave-particle duality experiments
Chithra Raj, Tushita Prasad, Anubhav Chaturvedi +8
Wave-particle duality is known to be equivalent to an entropic uncertainty relation based on the min- and max-entropies, which have a clear operational meaning in quantum cryptogra…
