Limitations on a device-independent key secure against a nonsignaling adversary via squashed nonlocality

M Winczewski, T Das, K Horodecki - Physical Review A, 2022 - APS
We initiate a systematic study to provide upper bounds on device-independent keys, secure
against a nonsignaling adversary (NSDI). We employ the idea of “squashing” on the secrecy …
