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…
Thermodynamic advancement in the causally inseparable occurrence of thermal maps
Tamal Guha, Mir Alimuddin, Preeti Parashar
Quantum mechanics allows the occurrence of events without having any definite causal order. Here, it is shown that the application of two different thermal channels in the causally…
Structure of passive states and its implication in charging quantum batteries
Mir Alimuddin, Tamal Guha, Preeti Parashar
In this article, in addition to the characterization of geometrical state spaces for the passive states, an operational approach has been introduced to distinguish them on their ch…
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…
