Entropic uncertainty relations for three measurements in the three-dimensional system. (a) Comparison between several bounds and entropic uncertainty with respect to a, including the maximal SCB (long-dashed black line), RPZ bound (dotted red line) and LMF bound (solid orange line). Dashed green line is for the theoretic result of state |0〉 and dashed-dotted blue line is for that of state |−1〉. (b) Comparison between the predicted measurement entropy, experiment results and SCB with respect to parameter a. The error bars use the standard error (SE).
