RT Journal Article T1 Optimal entropic uncertainty relation in two-dimensional Hilbert space A1 Sánchez-Ruiz, Jorge AB The exact lower bound on the sum of the information entropies is obtained for arbitrary pairs of observables in two-dimensional Hilbert space. The result coincides with that given by Garrett and Gull for the particular case of real transformation matrices and state vectors. A weaker analytical bound is also obtained.
