It has been theoretically proven by both the Hopfield neural network model and the quantum stochastic walk modelSchuld2014 (), that the walk always fully evolves to the sink state closest to the initial state in terms of the Hamming Distance, and if there are two sink states of an equal Hamming Distance to the initial state, the walk will end up with equal probabilities at the two sink states. With the increasing crossover between quantum information and machine learning, quantum simulation of neural networks has drawn unprecedentedly strong attention, especially for the simulation of associative memory in Hopfield neural networks due to their wide applications and relatively simple structures that allow easier mapping to the quantum regime. 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.

a number of theories of consciousness in existence, some of which are based on classical physics while some others require the use of quantum concepts.

Hopfield Model. One may wonder if the above results for the p-spin model would apply to more difficult problems. To answer this question, we have studied the Hopfield model (Seki and Nishimori, 2015), which has randomness in interactions, and the ground state is non-trivial (Amit et al., 1985a,b, 1987; Nishimori and Nonomura, 1996). 2019-02-07 The Hopfield model in a transverse field is investigated in order to clarify how quantum fluctuations affect the macroscopic behavior of neural networks.

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.
