Random-Receiver Quantum Communication
Some Sankar Bhattacharya, Ananda G. Maity, Tamal Guha +2
We introduce the task of random-receiver quantum communication, in which a sender transmits a quantum message to a receiver chosen from a list of n spatially separated parties. The…
Quantum theory is exclusive: a distributed computing setup
Sutapa Saha, Tamal Guha, Some Sankar Bhattacharya +1
The framework of distributed computing, consisting of several spatially separated input-output servers, has immense importance in distant data manipulation. One of the most challen…
Multi-copy adaptive local discrimination: Strongest possible two-qubit nonlocal bases
Manik Banik, Tamal Guha, Mir Alimuddin +3
Ensembles of composite quantum states can exhibit nonlocal behaviour in the sense that their optimal discrimination may require global operations. Such an ensemble containing N pai…
Operational Characterization of Multipartite Nonlocal Correlations
Sagnik Dutta, Amit Mukherjee, Manik Banik
Nonlocality, one of the most puzzling features of multipartite quantum correlation, has been identified as a useful resource for device-independent quantum information processing.…
Bell Nonlocality and the Reality of Quantum Wavefunction
Anandamay Das Bhowmik, Preeti Parashar, Manik Banik
Status of quantum wavefunction is one of the most debated issues in quantum foundations -- whether it corresponds directly to the reality or just represents knowledge or informatio…
Quantum Advantage for Shared Randomness Generation
Tamal Guha, Mir Alimuddin, Sumit Rout +3
Sharing correlated random variables is a resource for a number of information theoretic tasks such as privacy amplification, simultaneous message passing, secret sharing and many m…
