We demonstrate a scalable approach to addressing multiple atomic qubits for use in quantum information processing. Individually trapped 87 Rb atoms in a linear array are selectively manipulated with a single laser guided by a microelectromechanical beam steering system. Single qubit oscillations are shown on multiple sites at frequencies of Ӎ3.5 MHz with negligible crosstalk to neighboring sites. Switching times between the central atom and its closest neighbor were measured to be 6 -7 s while moving between the central atom and an atom two trap sites away took 10-14 s.
