Abstract:In this paper, we consider an alternative form of the uncertainty relation for quantum observables of discrete spectrum which makes use of so-called “information energy” as the measure of uncertainty. Then we apply this form of uncertainty relation to the particular case of two mutually orthogonal components of the spin-1/2 operator. We show that the use of this non-standard uncertainty measure simplifies the expression for spreads of observables and for the construction of the corresponding uncertainty relation.
