Publisher

Abstract

This paper presents a novel approach to quantum state simulation utilizing multi-layer neural networks. Traditional methods of quantum simulation, particularly those based on solving the Schrödinger equation, face significant computational challenges, especially for complex quantum systems with numerous qubits. This research proposes a framework where a multi-layer neural network is trained to approximate the dynamics of a quantum system, effectively mimicking the behavior of a quantum system without explicitly solving the underlying equations. The core of this method lies in the neural network's inherent ability to learn complex, non-linear mappings, allowing it to represent the time evolution dictated by the Schrödinger equation. We explore the architecture of the network, focusing on its ability to capture the intricate correlations within quantum states. The results demonstrate the potential for significantly faster and more efficient quantum state simulation compared to conventional approaches, offering a viable path toward simulating larger and more complex quantum systems.

Quantum-Inspired Entanglement-Based Neural Networks

Jincheng Zhang

This paper proposes a novel neural network architecture, termed Entanglement-Based Neural Networks (EBNNs), inspired by the principles of quantum entanglement. Conventional classical neural networks often face challenges in effectively capturing and representing intricate correlations within data, particularly when dealing with high-dimensional or complex datasets. The core idea behind EBNNs is to construct networks where nodes are interconnected in a manner that mirrors the correlated states observed in quantum entanglement, even across spatial separation. This is achieved through a specifically designed network topology that introduces dependencies between nodes, allowing for a more efficient representation of complex relationships. The network's structure is defined by a set of interconnected nodes, each possessing a state (s_i) represented by a real number. The connections between nodes are characterized by a correlation function (C_{ij}), which dictates the degree to which the state of node *j* is influenced by the state of node *i*. The architecture utilizes a layered approach, where layers are composed of interconnected nodes. The propagation of information through the network is governed by a modified version of the Hebbian learning rule, adapted to incorporate the entanglement-like correlation functions. This approach aims to improve the network's ability to learn and represent complex patterns by leveraging inherent correlations rather than relying solely on independent node activations. The key contributions of this work are the conceptual design of EBNNs and the formulation of the core mathematical framework for their implementation. We present a detailed description of the network architecture, the correlation function definition, and the learning rule, offering a foundation for further research and development in this area. Finally, we demonstrate the potential advantages of EBNNs in terms of improved learning efficiency and representation capacity.
