  Neutral atoms trapped by laser light are amongst the most promising
candidates for storing and processing information in a quantum computer or
simulator. The application certainly calls for a scalable and flexible scheme
for addressing and manipulating the atoms. We have now made this a reality by
implementing a fast and versatile method to dynamically control the position of
neutral atoms trapped in optical tweezers. The tweezers result from a spatial
light modulator (SLM) controlling and shaping a large number of optical
dipole-force traps. Trapped atoms adapt to any change in the potential
landscape, such that one can re-arrange and randomly access individual sites
within atom-trap arrays.
