1. A system for configuring an array of atoms for performing quantum computation, comprising:
an optical confinement system for arranging atoms in a first array state in a trap array, the optical confinement system comprising:
a holding trap array configured to hold a plurality of atoms, said holding trap array having at least three traps;
a first control acousto-optical deflector (AOD) and a second control AOD, wherein the first control AOD is configured to deflect the first laser beam in a first direction and the second control AOD is configured to deflect the first laser beam in a second direction different from the first direction;
an adjustable acoustic tone source configured to selectively apply a first plurality and a second plurality of acoustic tones to the first and the second control AODs, respectively, each tone having a discrete adjustable frequency, each frequency corresponding to at least one trap of the holding trap array, and
a first laser light source arranged to pass a beam through the first and the second control AODs;
a magneto-optical trap, the magneto-optical trap being configured to position an atom cloud to at least partially overlap with the plurality of traps;
a second laser light source for evolving at least some of the plurality of atoms in the trap array in the first array state into a second array state; and
an imaging device for observing the plurality of atoms in the second array state.
