Security of Device-independent Quantum Key Distribution under Sequential Attack
Pritam Roy, Souradeep Sasmal, Subhankar Bera +3
Device-independent quantum key distribution (DI-QKD) leverages nonlocal correlations to establish cryptographic keys between two honest parties while making minimal assumptions abo…
Unbounded Communication Power of a Qubit
Souradeep Sasmal, Som Kanjilal, Debarshi Das
Quantum mechanics enables information-processing advantages even at the level of a single qubit. A paradigmatic example is the 21 random access code (RAC), where a qubit outpe…
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…
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…
Robust self-testing of the partite maximally entangled state and observables
Ritesh K. Singh, Souradeep Sasmal, A. K. Pan
As quantum technologies continue to advance rapidly, the device-independent testing of the functioning of a quantum device has become increasingly important. Self-testing, a correl…
