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…
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…
Independence of work and entropy for equal energetic finite quantum systems: Passive state energy as an entanglement quantifier
Mir Alimuddin, Tamal Guha, Preeti Parashar
Although entropy is a necessary and sufficient quantity to characterize the order of work content for equal energetic (EE) states in the asymptotic limit, for the finite quantum sy…
Some no-go results in Quantum Thermodynamics
Tamal Guha, Mir Alimuddin, Preeti Parashar
Thermodynamics is one of the fascinating branches of traditional physics to certify the occurrence of many natural processes. On the other hand, quantum theory is the most acceptab…
