Nonlocal correlations in an asymmetric quantum network

Souradeep Sasmal, Shyam Sundar Mahato, Alok Kumar Pan

The nonlocality revealed in a multiparty multisource network Bell experiment is conceptually different than the standard multiparty Bell nonlocality involving a single common sourc…

Device-independent certification of degeneracy-breaking measurements

Prabuddha Roy, Shyam Sundar Mahato, Sumit Mukherjee +1

In a device-independent Bell test, the devices are considered to be black boxes and the dimension of the system remains unspecified. The dichotomic observables involved in such a B…

Device-independent randomness certification using multiple copies of entangled states

Shyam Sundar Mahato, A. K. Pan

We demonstrate to what extent many copies of maximally entangled two-qubit states enable for generating a greater amount of certified randomness than that can be certified from a s…

Sharing nonlocality in quantum network by unbounded sequential observers

Shyam Sundar Mahato, A. K. Pan

Of late, there has been an upsurge of interest in studying the sequential sharing of various forms of quantum correlations, viz., nonlocality, preparation contextuality, coherence,…

Device-independent certification of Hilbert space dimension using a family of Bell expressions

A. K. Pan, Shyam Sundar Mahato

Dimension witness provides a device-independent certification of the minimal dimension required to reproduce the observed data without imposing assumptions on the functioning of th…
