    "abstract": "The readout of the quantum spin state is a challenge for any spin-based\nquantum computing implementation. We propose a scheme, based on the achieved\ntechnique of single electron transistor (SET), to implement the readout of\nelectronic spin state inside a doped $C_{60}$ fullerene by means of the\nmagnetic dipole-dipole coupling and spin filters. In the presence of an\nexternal magnetic field, we show how to perform the spin state detection by\ntransforming the information contained in the spin state into the tunneling\ncurrent. The robustness of our scheme against sources of error is discussed.",
