Diagram of the quantum generalisation of a classical neuron with M inputs and N outputs. The superscripts inside the square brackets of the unitaries represent the number of qubits that the respective unitaries act on. U [M+1] is the unitary that represents the quantum neuron with an M-qubit input and U [N] is the fan-out gate that fans out the output in the final port of U [M+1] in a particular basis
