Abstract

Quantum state simulation is a cornerstone of quantum computing, aiming to accurately represent and manipulate the behavior of quantum systems. However, traditional methods of quantum state simulation, such as the Density Matrix Renormalization Group (DMRG) method and the Variational Quantum Eigensolver (VQE), often suffer from significant computational challenges, particularly as the size of the quantum system increases. This paper proposes a novel approach to quantum state simulation leveraging the power of Graph Neural Networks (GNNs). We represent a quantum state as a graph, where nodes correspond to individual quantum states and edges represent the correlations between them. A GNN is then trained to learn the complex relationships within the quantum state, enabling efficient and scalable simulation. Our method significantly reduces the computational burden associated with traditional techniques, offering a promising path towards practical quantum state simulation. The core claim is the utilization of graph neural networks' structural information for efficient quantum state simulation. The core mechanism involves representing quantum states as nodes in a graph and employing GNNs to learn relationships between them, facilitating efficient quantum state simulation.

The verification of quantum circuits is a critical step in ensuring the reliable execution of quantum computations. Traditional methods often struggle with the exponential complexity arising from the superposition and entanglement inherent in quantum mechanics. This work proposes a novel approach utilizing Graph Neural Networks (GNNs) to address this challenge. Quantum circuits are represented as graphs, where nodes correspond to quantum gates and edges represent data flow. The GNN learns to identify patterns within these graph representations that signify potential errors or deviations from the intended circuit behavior. This automated verification process offers a scalable solution compared to exhaustive simulation or analytical methods. The core of this approach lies in leveraging the expressive power of GNNs to capture complex correlations within the circuit structure, ultimately leading to more efficient and accurate verification.
