WebWe can use a neat PyTorch pipeline to create a neural network architecture. The network will need to be compatible in terms of its dimensionality when we insert the quantum layer (i.e. our quantum circuit). Since our quantum in this example contains 1 parameter, we must ensure the network condenses neurons down to size 1.
