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…
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…
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…
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…
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…
