Margenau-Hill distribution as a Necessary and Sufficient Signature of Measurement Incompatibility
Partha Patra, A. K. Pan
Measurement incompatibility and the negativity of quasi-probability distributions both demonstrate the signature of nonclassicality. However, their relations largely remained quali…
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…
Probing the robustness of various self-testing protocols for multipartite entangled states
Priyaranjan K. Jha, Ritesh K. Singh, A. K. Pan
Device-independent certification of multipartite entangled states plays a central role in a wide range of practical applications, including quantum networks, conference key agreeme…
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…
Scalable Self-Testing of Mutually Anticommuting Observables and Maximally Entangled Two-Qudits
Souradeep Sasmal, Ritesh K. Singh, Prabuddha Roy +1
The next frontier in device-independent quantum information lies in the certification of scalable and parallel quantum resources, which underpin advanced quantum technologies. We p…
