    "abstract": "Coherent oscillations between any two levels from four nuclear spin states of\nI=3/2 have been demonstrated in a nanometre-scale NMR semiconductor device,\nwhere nuclear spins are all-electrically controlled. Using this device, we\ndiscuss quantum logic operations on two fictitious qubits of the I=3/2 system,\nand propose a quantum state tomography scheme based on the measurement of\nlongitudinal magnetization, $M_z$.",
