    "abstract": "We propose two potentially practical schemes to carry out two-qubit quantum\ngates on endohedral fullerenes $N@C_{60}$ or $P@C_{60}$. The qubits are stored\nin electronic spin degrees of freedom of the doped atom $N$ or $P$. By means of\nthe magnetic dipolar coupling between two neighboring fullerenes, the two-qubit\ncontrolled-NOT gate and the two-qubit conditional phase gate are performed by\nselective microwave pulses assisted by refocusing technique. We will discuss\nthe necessary additional steps for the universality of our proposal. We will\nalso show that our proposal is useful for both quantum gating and the readout\nof quantum information from the spin-based qubit state.",
