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 find the free-energy in the thermodynamic limit of a one-dimensional XY model associated to a system of N qubits.

Quantum Associative Memory (QuAM) - a quantum variant of Associative Memory - employs a quantum system as a storage medium and two quantum algorithms for information storage and retrieval. Classical associative memories allow to find track candidates with a constant-time lookup, and therefore are commonly used for HEP real-time pattern recognition.. The storage capacity of the associative

Quantum neural networks are computational neural network models which are based on the principles of quantum mechanics. The first ideas on quantum neural computation were published independently in 1995 by Subhash Kak and Ron Chrisley, engaging with the theory of quantum mind, which posits that quantum effects play a role in cognitive function.

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. 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.

Memories expressed by spin configurations are embedded in the quenched random couplings. The Hopfield model exhibits different behaviors depending on the number of embedded memory patterns. 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.
