Contradictory entropic joint uncertainty relations for complementary
observables in two-level systems [PDF]
Alfredo LuisWe show that different entropic measures of fluctuations lead to contradictory uncertainty relations for two complementary observables. We apply Tsallis and R\'{e}nyi 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.View original: http://arxiv.org/abs/1306.5211
