Nonadditive generalization of the quantum Kullback-Leibler divergence for measuring the degree of purification
Sumiyoshi Abe
The Kullback-Leibler divergence offers an information-theoretic basis for measuring the difference between two given distributions. Its quantum analog, however, fails to play a cor…

Monotonic decrease of the quantum nonadditive divergence by projective measurements
Sumiyoshi Abe
Nonadditive (nonextensive) generalization of the quantum Kullback-Leibler divergence, termed the quantum q-divergence, is shown not to increase by projective measurements in an ele…
