Relation of properties of spin systems in graph states with characteristics of graphs is found. The geometric measure of entanglement of graph states is detected on IBM’s quantum computers and its relation with degree of vertexes of corresponding graphs is found. Geometric measure of entanglement of continuous variable is obtained. A method for detection of energy levels of arbitrary spin system on a quantum computer based on studies of evolution of only one probe spin is proposed. It opens a possibility to achieve quantum supremacy in solving eigenvalue problem with development of multi-qubit quantum computers. Product Description popup.authors Gnatenko Khrystyna P.
