        <label>Abstract</label>
        <p>The classical halting probability  introduced by Chaitin is generalized to quantum computations. (The quantum omega was invented in a meeting of G. Chaitin, A. Zeilinger and the author (K. S.) in a Viennese coffee house (Cafe Braeunerhof) in January 1991. Thus, the group should be credited for the original invention, whereas any blame should remain with the author.)</p>
