Connection between the contextuality breaking and incompatibility breaking qubit channels
Swati Kumari, Sumit Mukherjee, R. Prabhu
Contextuality and measurement incompatibility are two fundamental aspects of nonclassicality, and their manifestations in observed quantum correlations are often deeply interconnec…

Conditions for separability in multiqubit systems with an accelerating qubit using a conditional entropy
Harsha Miriam Reji, Hemant Shreepad Hegde, R. Prabhu
We study the separability in multiqubit pure and mixed Greenberger-Horne-Zeilinger (GHZ) and W states with an accelerating qubit using the Abe-Rajagopal (AR) -conditional entr…

Shareability of Quantum Correlations in a Many-Body Spin System with Two- and Three-Body Interactions
P. Kiran, Harsha Miriam Reji, Hemant Shreepad Hegde +1
The shareability of quantum correlations among the constituent parties of a multiparty quantum system is restricted by the quantum information theoretic concept called monogamy. De…
