Contradictory entropic joint uncertainty relations for complementary observables in two-level systems

Luis, Alfredo

Original · EN

We show that different entropic measures of fluctuations lead to contradictory uncertainty relations for two complementary observables. We apply Tsallis and Rényi entropies to the joint distribution emerging from a noisy simultaneous measurement of both observables as well as to the product of their individual statistics, either intrinsic or of operational origin.
