Quantum protocols were created to calculate the entanglement of these states. The entanglement  of pure and mixed states was found on IBM's quantum computers. The evolution of the average values of physical quantities was studied and its relation with transition energies of physical systems was examined. It is shown that for spin systems the transition energies are associated with a geometric measure of entanglement. The obtained results are important for the efficient usage of entanglement in quantum computing and quantum communications. Product Description popup.authors Gnatenko Khrystyna P. Kuzmak Andrij R.
