Tomiyama-type maps with a diagonal perturbation
Anindita Bera, Bihalan Bhattacharya, Dariusz Chruściński
We investigate a two-parameter family of linear maps on matrix algebras, constructed as diagonal perturbations of classical Tomiyama maps. Employing the Choi matrix method alongsid…
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…
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…
A class of Schwarz qubit maps with diagonal unitary and orthogonal symmetries
Dariusz Chruściński, Bihalan Bhattacharya
A class of unital qubit maps displaying diagonal unitary and orthogonal symmetries is analyzed. Such maps already found a lot applications in quantum information theory. We provide…
Detecting entanglement harnessing Lindblad structure
Vaibhav Chimalgi, Bihalan Bhattacharya, Suchetana Goswami +1
The problem of entanglement detection is a long standing problem in quantum information theory. One of the primary procedures of detecting entanglement is to find the suitable posi…
Measurement incompatibility and quantum advantage in communication
Debashis Saha, Debarshi Das, Arun Kumar Das +2
Measurement incompatibility stipulates the existence of quantum measurements that cannot be carried out simultaneously on single systems. We show that the set of input-output proba…
