a String diagrams of MOF representation based on BoW model, and b its corresponding quantum circuit with a single-qubit configuration for binary classification based on IQP ansatz. Dotted line boxes represent (i) initial quantum states, (ii) circuit parameters and (iii) controlled-not gates which indicating merge-dot. Open-wire that carries predicted class label is highlighted as blue line. c An overall process of quantum machine learning.
