    "abstract": "The errors caused by the transitions with large frequency offsets\n(nonresonant transitions) are calculated analytically for a scalable\nsolid-state quantum computer based on a one-dimensional spin chain with Ising\ninteractions between neighboring spins. Selective excitations of the spins are\nenabled by a uniform gradient of the external magnetic field. We calculate the\nprobabilities of all unwanted nonresonant transitions associated with the flip\nof each spin with nonresonant frequency and with flips of two spins: one with\nresonant and one with nonresonant frequencies. It is shown that these errors\noscillate with changing the gradient of the external magnetic field. Choosing\nthe optimal values of this gradient allows us to decrease these errors by 50%.",
