Genuine Multipartite Nonlocality for Arbitrary Input: Maximal Randomness Generation and Robust Self-Testing
Rajdeep Paul, Ranendu Adhikary, Alok Kumar Pan
Bell nonlocality provides the foundation for device-independent (DI) certification of quantum devices. We introduce a Bell inequality capable of identifying genuine multipartite no…
Exclusion reshapes the operational manifestation of preparation contextuality
Pritam Roy, Thansingh Jankawat, Ranendu Adhikary +1
Replacing the task of retrieval with exclusion changes how preparation contextuality manifests operationally under parity-oblivious constraints, with exclusion showing a quantum ad…
Hardy-type self-testing and exposedness of tripartite GHZ correlations
Smritikana Patra, Soumyajit Pal, Ranendu Adhikary
Nonlocality can be witnessed either through Bell-inequality violations or through logical contradictions such as Hardy's paradox. In the bipartite two input two outcome scenario, t…
Minimal Help, Maximal Gain: Environmental Assistance Unlocks Encoding Strength
Snehasish Roy Chowdhury, Sutapa Saha, Subhendu B. Ghosh +2
For any quantum transmission line, with smaller output dimension than its input, the number of classical symbols that can be reliably encoded is strictly suboptimal. In other words…
Multipartite Hardy paradox unlocks device-independent key sharing
Ranendu Adhikary, Mriganka Mandal
We introduce a device-independent quantum key distribution protocol for N parties, using the multipartite Hardy paradox to certify genuine multipartite nonlocality. Unlike traditio…
Self-testing of Nonmaximal Genuine Entangled States using Tripartite Hardy Relations
Ranendu Adhikary, Souradeep Sasmal, Arup Roy
We demonstrate that, in the tripartite scenario with all parties' local events being space-like separated, Hardy-type nonlocality constitutes a stronger manifestation of nonlocal c…
