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…
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…
Self-testing of multiple unsharpness parameters through sequential violations of non-contextual inequality
Rajdeep Paul, Souradeep Sasmal, A. K. Pan
The self-testing protocols refer to novel device-independent certification schemes wherein the devices are uncharacterised, and the dimension of the system remains unspecified. The…
Towards Necessary and sufficient state condition for violation of a multi-settings Bell inequality
Swapnil Bhowmick, Som Kanjilal, A. K. Pan +1
High dimensional quantum entanglement and the advancements in their experimental realization provide a playground for fundamental research and eventually lead to quantum technologi…
Kirkwood-Dirac Type Quasiprobabilities as Universal Identifiers of Nonclassical Quantum Resources
Kok Chuan Tan, Souradeep Sasmal
We show that a Kirkwood-Dirac type quasiprobability distribution is sufficient to reveal any arbitrary quantum resource. This is achieved by demonstrating that it is always possibl…
