Micro traps for quantum information processing and precision force sensing

We review recent experimental progress towards quantum information processing and precision force sensing using neutral atoms in micro traps. Microscopic potential structures as generated by optical or electronic microstructures (micro traps) allow for a versatile manipulation of quantum states of atoms and of ultracold atomic quantum gases. Most recent experimental results include the implementation of single-qubit-operations in both, optical and magnetic micro traps, as well as in the demonstration of matter-wave interferometer using Bose-Einstein condensates coherently split in micro traps.
