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…

Self-testing in a constrained prepare-measure scenario sans assuming quantum dimension
Ritesh K. Singh, Souradeep Sasmal, S. Nautiyal +1
We present a device-independent (DI) self-testing protocol in a constrained prepare-measure scenario, based on the bit parity-oblivious multiplexing (POM) task. In this scenari…

Constrained Measurement Incompatibility from Generalised Contextuality of Steered Preparation
Sumit Mukherjee, A. K. Pan
In a bipartite Bell scenario involving two local measurements per party and two outcome per measurement, the measurement incompatibility in one wing is both necessary and sufficien…
