Resumo:We review recent progress towards implementing quantum information processing protocols using electron and nuclear magnetic resonance in the molecule N-14@C-60. Using conventional spectrometers, we measure the errors inherent in quantum manipulations of spins. By applying composite pulses, we correct the dominant error to a high degree. Identifying a two qubit computational basis out of the electron and oF nuclear spin levels of N-14@C-60, we implement an ultrafast phase gate on the nuclear qubit by exciting an electron spin transition.
