Abstract

We demonstrate the trapping and manipulation of single neutral atoms in reconfigurable arrays of optical tweezers. Our approach offers unparalleled speed by using a Texas instruments digital micro-mirror device as a holographic amplitude modulator with a frame rate of 20 000 per second. We show the trapping of static arrays of up to 20 atoms, as well as transport of individually selected atoms over a distance of 25 μm with laser cooling and 4 μm without. We discuss the limitations of the technique and the scope for technical improvements.

Highlights

  • Single neutral atoms are promising candidates for physically realising quantum bits, the fundamental unit of quantum information

  • The most common traps for neutral atoms are those based on the optical dipole force [8, 9]

  • Several approaches have been tried for creating reconfigurable traps, for example, acousto-optic deflectors (AODs) [13,14,15] and liquid crystal spatial light modulators (SLMs) [16,17,18]
