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…

Restrictions to realize multiport quantum dense coding in a many-body quantum spin system with two- and three-body interactions
P. Kiran, Hemant Shreepad Hegde, Harsha Miriam Reji +1
Quantum information with many-body quantum spin systems has, from time to time, given intriguing and intuitive outcomes to our understanding of multiport quantum communications. We…

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…
