    "abstract": "We have found that encapsulated atoms in fullerene molecules, which carry a\nspin, can be used for fast quantum computing. We describe the scheme for\nperforming quantum computations, going through the preparation of the qubit\nstate and the realization of a two-qubit quantum gate. When we apply a static\nmagnetic field to each encased spin, we find out the ideal design for the\npreparation of the quantum state. Therefore, adding to our system a time\ndependent magnetic field, we can perform a phase-gate. The operational time\nrelated to a $\\pi-$phase gate is of the order of $ns$. This finding shows that,\nduring the decoherence time, which is proportional to $\\mu s$, we can perform\nmany thousands of gate operations. In addition, the two-qubit state which\narises after a $\\pi-$gate is characterized by a high degree of entanglement.\nThis opens a new avenue for the implementation of fast quantum computation.",
