Abstract
We have got a lot of experience with computer simulations of Hop?eld’s and holo-
graphic neural net models. Starting with these models, an analogous quantum in-
formation processing system, called quantum associative network, is presented in this
article. It was obtained by translating an associative neural net model into the mathe-
matical formalism of quantum theory in order to enable microphysical implementation
of associative memory and pattern recognition. In a case of successful quantum im-
plementation of the model, expected bene?ts would be signi?cant increase in speed, in
miniaturization, in e?ciency of performance, and in memory capacity, mainly because
of additionally exploiting quantum-phase encoding.
Keywords:
Hop?eld model, associative neural network, quantum associative network, holography,
quantum computing
1 Introduction
In previous articles [1, 2, 3] we have presented in detail how and where the mathematical
formalism of associative neural network models by Hop?eld [4] and Haken [5] is analogous to
the mathematical formalism of quantum theory (similar comparative studies can be found in
[6, 7, 8]). In this article, an original and fundamental information processing system is pre-
sented, and an example of a quantum neural-network-like information processing “algorithm”
is described in a way understandable for computer scientists, physicists and neuroscientists.
We have chosen this “algorithm”, simple but nevertheless e?ective, technically realizable,
and roughly (on global scale) bio
