Characterizing pairwise swapping capabilities of dense coding channels

Abhishek Muhuri, Nirman Ganguly, Aditi Sen De +1

We introduce a novel multipartite entanglement-assisted classical communication task, referred to as dense coding swapping, in which legitimate parties collaboratively swap the den…

Revocation and Reconstruction of Shared Quantum States

Prakash Mudholkar, Chiranjeevi Vanarasa, Indranil Chakrabarty +1

The problem of revocation of quantum states after sharing is interesting and we ask: Is it possible for a dealer to revoke the state once shared, before the reconstruction process?…
