The Quantum Generative Adversarial Network algorithm.
The qGAN  is a hybrid quantum-classical algorithm used for generative modeling tasks.
This adaptive algorithm uses the interplay of a generative
GenerativeNetworkand a discriminative
DiscriminativeNetworknetwork to learn the probability distribution underlying given training data.
These networks are trained in alternating optimization steps, where the discriminator tries to differentiate between training data samples and data samples from the generator and the generator aims at generating samples which the discriminator classifies as training data samples. Eventually, the quantum generator learns the training data's underlying probability distribution. The trained quantum generator loads a quantum state which is a model of the target distribution.
