TY - JOUR ID - 1759981 AU - Plávala, Martin - Ziman, Mário PY - 2020 TI - Popescu-Rohrlich box implementation in general probabilistic theory of processes JF - Physics Letters A VL - 384 IS - 16 SP - 126323 EP - 126323 PB - Elsevier SN - 03759601 KW - quantum information KW - quantum nonlocality UR - https://doi.org/10.1016/j.physleta.2020.126323 N2 - It is shown that Popescu-Rohrlich nonlocal boxes (beating the Tsirelson bound for Bell inequality) do exist in the existing structures of both quantum and classical theory. In particular, we design an explicit example of measure-and-prepare nonlocal (but no-signaling) channel being the realization of nonlocal and no-signaling Popescu-Rohrlich box within the generalized probabilistic theory of processes. Further we present a post-selection-based spatially non-local implementation and show it does not require truly quantum resources, hence, improving the previously known results. Interpretation and potential (spatially non-local) simulation of this form of process nonlocality and the protocol is discussed. ER -
