    "abstract": "We present a composite pulse controlled phase gate which together with a bus\narchitecture improves the feasibility of a recent quantum computing proposal\nbased on rare-earth-ion doped crystals. Our proposed gate operation is tolerant\nto variations between ions of coupling strengths, pulse lengths, and frequency\nshifts, and it achieves worst case fidelities above 0.999 with relative\nvariations in coupling strength as high as 10% and frequency shifts up to\nseveral percent of the resonant Rabi frequency of the laser used to implement\nthe gate. We outline an experiment to demonstrate the creation and detection of\nmaximally entangled states in the system.",
