Uncertainty relations based on mutually unbiased measurements

Quantum Physics 2015-06-09 v1

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 ρ\rho 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 R\'{e}nyi and Tsallis entropies.
