A study on Heisenberg-Weyl linear maps
Saikat Patra, Bihalan Bhattacharya
Heisenberg-Weyl operators provide a Hermitian generalization of Pauli operators in higher dimensions. Positive maps arising from Heisenberg-Weyl operators have been studied along w…

Revealing hidden nonlocality and preparation contextuality for an arbitrary input Bell inequality
Asmita Kumari, Saikat Patra
In recent years, the activation of hidden nonlocality for a mixed entangled state, admitting a local model, has gained considerable interest. In this paper, we study the activation…

Infinite dimensional dynamical maps
Bihalan Bhattacharya, Uwe Franz, Saikat Patra +1
Completely positive trace preserving maps are widely used in quantum information theory. These are mostly studied using the master equation perspective. A central part in this theo…
