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 $$d+1$$ MUMs on any density operator $$\rho $$ in $${\mathbb {C}}^{d}$$ , 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. [ABSTRACT FROM AUTHOR]
