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…
Nonlocality Without Entanglement: Quantum Theory and Beyond
Some Sankar Bhattacharya, Sutapa Saha, Tamal Guha +1
Quantum nonlocality without entanglement (Q-NWE) encapsulates nonlocal behavior of multipartite product states as they may entail global operation for optimal decoding of the class…
The principle of information symmetry constrains the state-space in any physical theory
Manik Banik, Sutapa Saha, Tamal Guha +4
Symmetry shares an entwined history with the structure of physical theory. We propose a consequence of symmetry towards the axiomatic derivation of Hilbert space quantum theory. We…
Allowed and Forbidden Bipartite Correlations from Thermal States
Tamal Guha, Mir Alimuddin, Preeti Parashar
The strong connection between correlations and quantum thermodynamics raises a natural question about the preparation of correlated quantum states from two copies of a thermal qubi…
Bound on Ergotropic Gap for Bipartite Separable States
Mir Alimuddin, Tamal Guha, Preeti Parashar
Presence of correlations among the constituent quantum systems has a great relevance in thermodynamics. Significant efforts have been devoted to investigate the role of correlation…
