A quantum JensenShannon graph kernel for unattributed graphs
We compute a density matrix for a graph using the continuous-time quantum walk. We compute the quantum JensenShannon divergence between graph density matrixes. We define a quantum JensenShannon graph kernel using the quantum divergence. We evaluate the performance of our quantum kernel on standard graph datasets. We demonstrate the effectiveness of the proposed quantum kernel.
