Memory attacks in network nonlocality and self-testing
We study what can or cannot be certified in communication scenarios where the assumption
of independence and identical distribution (iid) between experimental rounds fails. In this …

Shared randomness allows violation of macroscopic realism using a single measurement
S Sarkar - arXiv preprint arXiv:2310.15253, 2023 - arxiv.org
Macro-realistic description of systems is based majorly on two basic intuitions about the
classical world, namely, macrorealism per se, that is, the system is always in a distinct state …
