Recently quantum states discrimination has been frequently studied. In thispaper we study them from the other way round, the likeness of two quantumstates. The fidelity is used to describe the likeness of two quantum states.Then we presented a scheme to obtain the fidelity of two unknown qubitsdirectly from the integral area of the spectra of the assistant qubit(spin) onan NMR Quantum Information Processor. Finally we demonstrated the scheme on athree-qubit quantum information processor. The experimental data are consistentwith the theoretical expectation with an average error of 0.05, which confirmsthe scheme.Comment: 3 pages, 4 figure
