Witnessing Genuine Mutipartite Non-locality
Some Sankar Bhattacharya, Arup Roy, Amit Mukherjee +1
Genuine multipartite nonlocality is a salient feature of quantum systems, empowering the security of multi-party device independent cryptographic protocols. Given a correlation, ch…
GHZ correlation provides secure Anonymous Veto Protocol
Ramij Rahaman, Guruprasad Kar
Anonymous Veto (AV) and Dining cryptographers (DC) are two basic primitives for the cryptographic problems where the main aim is to hide the identity of the senders of the messages…
Necessary Condition for Local Distinguishability of Maximally Entangled States: Beyond Orthogonality Preservation
Tanmay Singal, Ramij Rahman, Sibasish Ghosh +1
The (im)possibility of local distinguishability of orthogonal multipartite quantum states still remains an intriguing question. Beyond , the pr…
Mixed graph states
Constanza Riera, Ramij Rahaman, Matthew G. Parker
We have generalised the concept of graph states to what we have called mixed graph states, which we define in terms of mixed graphs, that is graphs with both directed and undirecte…
