• Abstract: We develop a heuristic graph coloring approximation algorithm that uses the D-Wave 2X as an independent set sampler and evaluate its performance against a fully classical implementation. A randomly generated set of small but hard graph instances serves as our test set. Our performance analysis suggests limited quantum advantage in the hybrid quantum-classical algorithm. The quantum edge holds over multiple metrics and suggests that graph problem applications are a good fit for quantum annealers.

  We propose a hybrid quantum-classical algorithm for the NP-complete problem of determining if two graphs are minor of one another. We find a graph embedding that allows trading between the one-shot classification accuracy and the amount of input squeezing. We introduce a new classical algorithm based on graph spectra, which we show outperforms various well-known graph-similarity algorithms.

  We propose quantum graph convolutional networks (QuanGCN), which learns the local message passing among nodes with the sequence of crossing-gate quantum operations. To mitigate the inherent noises from modern quantum devices, we apply sparse constraint to sparsify the nodes' connections. Our QuanGCN is functionally comparable or even superior than the classical algorithms on several benchmark graph datasets.
