Quantum entanglement inferred by the principle of maximum Tsallis entropy
Sumiyoshi Abe, A. K. Rajagopal
The problem of quantum state inference and the concept of quantum entanglement are studied using a non-additive measure in the form of Tsallis entropy indexed by the positive param…

Implications of Form Invariance to the Structure of Nonextensive Entropies
A. K. Rajagopal, Sumiyoshi Abe
The form invariance of the statement of the maximum entropy principle and the metric structure in quantum density matrix theory, when generalized to nonextensive situations, is sho…
