Jan 19, 2021 · Variational classifier¶ Author: PennyLane dev team. Last updated: 19 Jan 2021. In this tutorial, we show how to use PennyLane to implement variational quantum classifiers - quantum circuits that can be trained from labelled data to classify new data samples. The architecture is inspired by Farhi and Neven (2018) as well as Schuld et al. (2018)
