%X The high expectations regarding the computational potential of quantum computation stem from quantum mechanical features,such as the principle of superposition,the phenomenon of entanglement,the destructive and constructive interference.Besides the presumed advantages of quantum computation over classical computation,there exist impediments that appear to be affecting the former but not the latter.One of them are the two uncertainty principles traditionally ascribed to Werner Heisenberg.The uncertainty principle formulated originally by Heisenberg pertains to the inability of measuring a quantum system with non-quantum instruments without affecting it.This principle is different from the later development postulating an inherent inability of non-commuting observables to be measured precisely.At present state of technological development and within the current formulation and interpretation of quantum mechanics,both versions of the uncertainty affect the speed attainable by a quantum computer.Recently,the two uncertainty principles have received more attention.In his improvement to Heisenberg’s principle,Ozawa took into account both types of uncertainty mentioned above.Furthermore,research into entropic uncertainty has shown that Heisenberg’s uncertainty can be seen as a lower bound of Hirschmann’s uncertainty,thereby indicating that quantum computation may need to consider other types of uncertainties,such as information uncertainty,as well.
