Certified quantum supremacy in entanglement-assisted prepare-measure random-access-code
Rajdeep Paul, Prabuddha Roy, A. K. Pan
We develop a family of semi-device-independent (SDI) entanglement-assisted prepare-measure (PM) communication games involving two parties, within the random-access…
Robust self-testing based on Gisin's arbitrary-input Bell inequality
Rajdeep Paul, Alok Kumar Pan
Self-testing refers to the strongest device-independent (DI) certification method that validates the nature of a quantum system and devices solely based on the observed statistics.…
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…
Semi-device-independent self-testing of unitary operations
Rajdeep Paul, Prabuddha Roy, A. K. Pan
We present a hitherto unexplored semi-device-independent (SDI) self-testing protocol designed to certify unitary operations within a variant of prepare-measure framework. We consid…
Robust self-testing and certified randomness based on chained Bell inequality
Rajdeep Paul, Sneha Munshi, Alok Kumar Pan
Self-testing is the strongest certification procedure that uniquely characterizes the physical system based on the observed statistics, without any knowledge of the inner workings…
