Abstract

Two potential schemes for carrying out two-qubit quantum gates on endohedral fullerenes N@C60 or P@C60 were presented. The qubits were stored in electronic spin degrees of freedom of the doped atom N or P. Using magnetic dipolar coupling between two neighbouring fullerenes, the two qubit controlled NOT gates and the two-qubit conditional phase gate were performed by means of selective microwave pulses assisted by the refocusing technique. The necessary additional steps meant for the universality of the schemes were discussed. It was shown that the scheme is useful for both quantum gating and the readout of quantum information from the spin-based qubit state.
