We have found that encapsulated atoms in fullerene molecules, which carry a spin, can be used for fast quantum computing. We describe the scheme for performing quantum computations, going through the preparation of the qubit state and the realization of a two-qubit quantum gate. When we apply a static magnetic field to each encased spin, we find out the ideal design for the preparation of the quantum state. Therefore, adding to our system a time dependent magnetic field, we can perform a phase-gate. The operational time related to a π-phase gate is of the order of ns. This finding shows that, during the decoherence time, which is proportional to μs, we can perform many thousands of gate operations. In addition, the two-qubit state which arises after a π-gate is characterized by a high degree of entanglement. This opens a new avenue for the implementation of fast quantum computation.
