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.

In this paper, we introduce quantum algorithms for a recurrent neural network, 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 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’s classical neural networks [1] have been intensely investigated and modeled for cognitive neurosciences [2]. It has been recently shown that Feynman’s propagator version of quantum theory is analogous to Hopfield’s model of classical associative neural network [3] - which is outlined in the first part of Quantum Hopfield network Consider a model with rank-pmatrix of interactions and no longitudinal field (hi=0):ref.31 (cf.rk Jik=Nfor SK model), where are taken to be independent and identically distributed (i.i.d.) random variables of unit variance. The coupling among the sigma_i^z is a long range two bodies random interaction.

A Hopfield network is an associative memory, which is different from a pattern classifier, the task of a perceptron. 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.

the model converges to a stable state and that two kinds of learning rules can be used to find appropriate network weights. 13.1 Synchronous and asynchronous networks A relevant issue for the correct design of recurrent neural networks is the ad-equate synchronization of the computing elements. In the case of McCulloch- Hopfield networks were invented in 1982 by J.J. Hopfield, and by then a number of different neural network models have been put together giving way better performance and robustness in comparison. 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.
