Read reviews from world’s largest community for readers. 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.

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

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. Similar to a classical Hopfield network, the quantum neurons are fully connected to each other, meanwhile, a self-loop is forbidden. We examine a quantum Hopfield neural-network model in the presence of trimodal random transverse fields and random neuronal thresholds within the method of statistical physics.

2014-08-26 · With the overwhelming success in the field of quantum information in the last decades, the ‘quest’ for a Quantum Neural Network (QNN) model began in order to combine quantum computing with the striking properties of neural computing. This article presents a systematic approach to QNN research, which so far consists of a conglomeration of ideas and proposals. Concentrating on Hopfield-type

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. A candidate to show a quantum advantage is believed to be quantum machine learning (QML) [4, 12], a field of research at the interface between quantum information processing and machine learning. Even though machine learning is an important tool that is widely used to process data and extract information from it [ 4 ], it also faces its limits. Abstract: The Hopfield model in a transverse field is investigated in order to clarify how quantum fluctuations affect the macroscopic behavior of neural networks. Using the Trotter decomposition and the replica method, we find that the $\alpha$ (the ratio of the number of stored patterns to the system size)-$\Delta$ (the strength of the transverse field) phase diagram of this model in the A quantum Hopfield model with a random transverse field and a random neuronal threshold is investigated by use of the statistical physics method.

Our goal with this paper is to elucidate the close connection between Hopfield networks and adiabatic quantum computing. Focusing on their use in problem solving, we point out that the energy functions minimized by Hopfield networks are essentially identical to those minimized by adiabatic quantum computers. To practically illustrate this, we consider a simple textbook problem, namely the k
