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…

Sharing preparation contextuality in Bell experiment by arbitrary pair of sequential observers

Asmita Kumari, Alok Kumar Pan

Based on the quantum violation of bipartite Bell inequality, it has been demonstrated that the sharing of non-locality can be demonstrated for at most two sequential observers at o…

Leggett-Garg test of macrorealism using indefinite causal order of measurements

A. K. Pan

Macrorealism is a belief that constitutes the core of our perception of reality in the everyday world. The Leggett-Garg (LG) test is a conceptually elegant approach for probing the…

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…

Non-separable Optical Beam Shifts and Emergence of Position-position Classical entanglement

Niladri Modak, S Ashutosh, Shyamal Guchhait +3

Under the introduction of any interface in its trajectory, an optical beam experiences polarization-dependent deflections in the longitudinal and transverse directions with respect…

Projective measurements under qubit quantum channels

Javid Naikoo, Subhashish Banerjee, A. K. Pan +1

The action of qubit channels on projective measurements on a qubit state is used to establish an equivalence between channels and properties of generalized measurements characteriz…
