Abstract

We report techniques for the fabrication of multi-zone linear RF Paul traps which exploit the machinability and electrical conductivity of bulk doped silicon. The approach was verified by trapping and Doppler cooling 24Mg+ ions in two trap geometries: a single-zone 2-layer trap and a multi-zone surface-electrode trap. From the measured ion motional heating rate we determine an electric field spectral density at the ion of approximately 1 × 10-10 (V /m)2 Hz−1 at ωz /2π {math equals} 1.125 MHz when the ion lies 40 υm above the electrode surface. One application of these devices is controlled manipulation of atomic ion qubits, the basis of one form of quantum information processing.
