    "abstract": "A proposal for a scalable, solid-state implementation of a quantum computer\nis presented. Qubits are fluorine nuclear spins in a solid crystal of\nfluorapatite [Ca_5 F(PO_4)_3] with resonant frequencies separated by a large\nfield gradient. Quantum logic is accomplished using nuclear-nuclear dipolar\ncouplings with decoupling and selective recoupling RF pulse sequences. Magnetic\nresonance force microscopy is used for readout. As many as 300 qubits can be\nimplemented in the laboratory extremes of T=10 mK and B_0=20 T with the\nexisting sensitivity of force microscopy.",
