Query: Remarks on the nature of quantum computation   Two models of computer, a quantum and a classical "chemical machine" designed
to compute the relevant part of Shor's factoring algorithm are discussed. The
comparison shows that the basic quantum features believed to be responsible for
the exponential speed-up of quantum computations possess their classical
counterparts for the hybrid digital-analog computer. It is argued that the
measurement errors which cannot be fully corrected make the computation not
efficient for both models.
