Detecting quantum resources in a semi-device independent framework
Shubhayan Sarkar, Chandan Datta
We investigate whether one can detect the presence of a quantum resource in some operational task or equivalently whether every quantum resource provides an advantage over its free…
Witnessing network steerability of every bipartite entangled state without inputs
Shubhayan Sarkar
Quantum steering is an asymmetric form of quantum nonlocality where one can detect whether a measurement on one system can steer or change another distant system. It is well-known…
One-sided DI-QKD secure against coherent attacks over long distances
Michele Masini, Shubhayan Sarkar
Quantum Key Distribution (QKD) is a technique enabling provable secure communication but faces challenges in device characterization, posing potential security risks. Device-Indepe…
Model-independent inference of quantum interaction from statistics
Shubhayan Sarkar
Any physical theory aims to establish the relationship between physical systems in terms of the interaction between these systems. However, any known approach in the literature to…
Almost device-independent certification of GME states with minimal measurements
Shubhayan Sarkar, Alexandre C. Orthey, Gautam Sharma +2
Device-independent certification of quantum states enables the characterization of states within a device under minimal physical assumptions. A major problem in this regard is to c…
