Based on a recent proposal [Phys. Rev. A 71, 062337 (2005)], we have experimentally realized two-photon polarization qutrits by using nonmaximally entangled states and linear optical transformations. By this technique, high-fidelity mutually unbiased qutrits are generated at a high brilliance level.
