A Block-Ring connected Topology of Parameterized Quantum Circuits

2023 · arXiv (Cornell University)

It is essential to select efficient topology of parameterized quantum circuits (PQCs) in variational quantum algorithms (VQAs). However, there are problems in current circuits, i.e. optimization difficulties caused by too many parameters or performance is …

Rotation- and Permutation-Equivariant Quantum Graph Neural Network for 3D Graph Data

2025 · IEEE Transactions on Pattern Analysis and Machine Intelligence

Equivariant quantum graph neural networks (EQGNNs) offer a potentially powerful method to process graph data. However, existing EQGNN models only consider the permutation symmetry of graphs, and failing to fully exploit the geometric and non-geometric …
