Former student Sophia Day (Vanderbilt '17) graciously takes us through a homework assignment for my Human Memory class. The assignment involves working with Quantum machine learning is a new buzzword in quantum computing. This emerging field asks — amongst other things — how we can use quantum computers for intelligent data analysis. At Xanadu we Lecture from the course Neural Networks for Machine Learning, as taught by Geoffrey Hinton (University of Toronto) on Coursera in 2012.

Proposed by John Hopfield in 1982, the Hopfield network is a recurrent content-addressable memory that has binary threshold nodes which are supposed to yield a local minimum. It is a fully autoassociative architecture with symmetric weights without any self-loop. Quantum computing allows for the potential of significant advancements in both the speed and the capacity of widely used machine learning techniques. 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.

the recalling processes of the Hopfield model governed by the Glauber-dynamics at the finite temperature were already reported. However, we might extend the `thermal noise' to the quantum-mechanical variant. In this talk, in terms of the stochastic process of quantum-mechanical Markov chain Monte Carlo method (the quantum MCMC),

Quantum hopfield model

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. network [9] and, equivalent to it, Peruš’s model of Hopfield-like quantum associative neural network [3]. 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.

To my knowledge, they are mostly introduced and mentioned in textbooks when approaching Boltzmann Machines and Deep Belief Networks, since they are built upon Hopfield’s work. The Hopfield model in a transverse field is investigated in order to clarify how quantum fluctuations affect the macroscopic behavior of neural networks.
