QUANTUM NEURAL NETS

The capacity of classical neurocomputers is limited by the number of c lassical degrees of freedom, which is roughly proportional to the size of the computer. By contrast, a hypothetical quantum neurocomputer ca n implement an exponentially larger number of the degrees of freedom w ithin the same size. In this paper an attempt is made to reconcile the linear reversible structure of quantum evolution with nonlinear irrev ersible dynamics for neural nets.
