The implementation of the readout of an electronic spin state inside a doped C60 fullerene, based on single-electron transistor, was investigated using magnetic dipole-dipole coupling and spin filters. The detection of spin state was performed by transforming the information contained in the spin state into the tunneling current in presence of an external magnetic field. When the charged fullerene was moved close to a fullerene with dopant atoms, outside spin, was found to interact with inside spin, by magnetic dipole-dipole. The results show that by strictly controlling the tunneling of electron and implementing ESR pulses, a promising method for the readout of fullerene-based quantum computation is achieved.
