Quantum Rényi entropy
The quantum Rényi entropy is a one-parameter family of entropy measures on quantum states that generalizes the von Neumann entropy, recovering it as α approaches 1.
Rényi entropy
Rényi entropy, also called Rényi information, is a one-parameter family of information measures introduced by Alfréd Rényi that generalizes Shannon entropy and reduces to it as its order approaches 1.
Tsallis entropy
Tsallis entropy, also called nonextensive entropy, is a one-parameter family of entropies proposed by Constantino Tsallis in 1988, generalizing Boltzmann–Gibbs–Shannon entropy and underpinning nonextensive statistical mechanics.
