    "abstract": "We report an experimental confirmation of the power-law relationship between\nthe critical anisotropy parameter and ion number for the linear-to-zigzag phase\ntransition in an ionic crystal. Our experiment uses laser cooled calcium ions\nconfined in a linear radio-frequency trap. Measurements for up to 10 ions are\nin good agreement with theoretical and numeric predictions. Implications on an\nupper limit to the size of data registers in ion trap quantum computers are\ndiscussed.",
