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 ¹⁴N@C₆₀. 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 ¹⁴N@C₆₀, we implement an ultrafast phase gate on the nuclear qubit by exciting an electron spin transition.
