    "abstract": "We have studied a system composed by two endohedral fullerene molecules. We\nhave found that this system can be used as good candidate for the realization\nof Quantum Gates Each of these molecules encapsules an atom carrying a\nspin,therefore they interact through the spin dipole interaction. We show that\na phase gate can be realized if we apply on each encased spin static and time\ndependent magnetic field. We have evaluated the operational time of a\n$\\pi$-phase gate, which is of the order of ns. We made a comparison between the\ntheoretical estimation of the gate time and the experimental decoherence time\nfor each spin. The comparison shows that the spin relaxation time is much\nlarger than the $\\pi$-gate operational time. Therefore, this indicates that,\nduring the decoherence time, it is possible to perform some thousands of\nquantum computational operations. Moreover, through the study of concurrence,\nwe get very good results for the entanglement degree of the two-qubit system.\nThis finding opens a new avenue for the realization of Quantum Computers.",
