Uncertainty relations based on mutually unbiased measurements

preprint2014arXivOpen access

Abstract

We derive uncertainty relation inequalities according to the mutually unbiased measurements. Based on the calculation of the index of coincidence of probability distribution given by d+1d+1 MUMs on any density operator ρρ in Cd\mathbb{C}^{d}, both state-dependent and state-independent forms of lower entropic bounds are given. Furthermore, we formulate uncertainty relations for MUMs in terms of Rényi and Tsallis entropies.
