Providing a comprehensive introduction to quan 2021-03-19 The quantum model of the brain proposed by Ricciardi and Umezawa is extended to dissipative dynamics in order to study the problem of memory capacity. It is shown that infinitely many vacua are accessible to memory printing in a way that in sequential information recording the storage of a new information does not destroy the previously stored ones, thus allowing a huge memory capacity. 2021-04-09 The Hopfield model in a transverse field is investigated in order to clarify how quantum fluctuations affect the macroscopic behavior of neural networks. 2020-02-27 · Quantum Hopfield neural network We now extend the Hopfield network into a quantum regime that is designed in combination with quantum computing theory. In this network, the neurons are two-state quantum bits.

2017-10-10 · Here we employ quantum algorithms for the Hopfield network, which can be used for pattern recognition, reconstruction, and optimization as a realization of a content-addressable memory system. We show that an exponentially large network can be stored in a polynomial number of quantum bits by encoding the network into the amplitudes of quantum states.

Quantum hopfield model

A Hopfield network (or Ising model of a neural network or Ising–Lenz–Little model) is a form of recurrent artificial neural network and a type of spin glass system popularised by John Hopfield in 1982 as described earlier by Little in 1974 based on Ernst Ising 's work with Wilhelm Lenz on Ising Model.

In this section we shall outline Peruš’s model, based on the direct mathematical correspondence between classical neural and quantum variables and corresponding Hopfield-like classical and quantum equations [3,6]: the Hopfield dielectric – in quantum mechanics a model of dielectric consisting of quantum harmonic oscillators interacting with the modes of the quantum electromagnetic field.

The Trotter decomposition is used to reduce the problem to that of an equivalent classical random Ising model.
