The geometric measure of entanglement of variational quantum states isstudied on the basis of its relation with the mean value of spin. We examinen-qubit quantum states prepared by a variational circuit with a layer formed bythe rotational gates and two-qubit controlled phase gates. The variationalcircuit is a generalization of that used for preparing quantum GenerativeAdversarial Network states. The entanglement of a qubit with other qubits inthe variational quantum states is determined by the angles of rotational gatesthat act on the qubit and qubits entangled with it by controlled phase gatesand also their parameters. In the case of one layer variational circuit, thestates can be associated with graphs with vertices representing qubits andedges corresponding to two-qubit gates. The geometric measure of entanglementof a qubit with other qubits in the quantum graph state depends on theproperties of the vertex that represents it in the graph, namely it depends onthe vertex degree. The dependence of the geometric measure of entanglement ofvariational quantum states on their parameters is quantified on IBM's quantumcomputer.
