Representation of Graph states by RBMs. a Graph representation of an example graph state. b Representation of the graph state with a restricted Boltzmann machine. One hidden neuron with the Hadamard weight function W H (explicit form given in Eq. (1) of the text) simulates the correlation in the wave function between each pair of connected qubits in any graph states
