Manipulation of quantum information in N@C60 using electron and nuclear magnetic resonance

We review recent progress towards implementing quantum information processing protocols using electron and nuclear magnetic resonance in the molecule 14 N@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 nuclear spin levels of 14 N@C 60 , we implement an ultrafast phase gate on the nuclear qubit by exciting an electron spin transition.
