Entanglement of graph states of spin system with Ising interaction and its quantifying on IBM's quantum computer (2012.05986v2)
Published 10 Dec 2020 in quant-ph
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.
