Abstract

The Tsallis entropy defines an important generalization of the usual concept of entropy which depends on parameter α. Our goal is to establish a connection between the quantum uncertainty principle and the Tsallis entropy for single discrete observables. In particular, we show that there exist a generalized uncertainty bound reached in order to appropriately express the quantum uncertainty principle in terms of the Tsallis entropy. This kind of connection forms an initial important step towards finding an important application of this α-entropy in the area of quantum communication particularly in quantum key distribution for which they have not been extensively investigated.
