- Abstract: We consider graph states generated by operator of evolution with Ising
Hamiltonian. The geometric measure of entanglement of a spin with other spins
in the graph state is obtained analytically and quantified on IBM's quantum
computer, IBM Q Valencia. The results of quantum calculations are in good
agreement with the theoretical ones. We conclude that the geometric measure of
entanglement of a spin with other spins in the graph state is related with
degree of vertex representing the spin in the corresponding graph.
