Spin-1 tunneling and splitting of energy level as result of tunneling are observed explicitly on IBM’s quantum computer, ibmq-bogota. The spin-1 is realized with two spins-1/2. We detect oscillations of spin-1 between opposite directions in the result of tunneling on the basis of studies of time dependence of the mean value of z-component of spin-1 on the quantum device. The energy level splitting is observed quantifying on the IBM’s quantum computer the eigenvalues of Hamiltonian which describes the spin tunneling.
