  • Abstract: ooling and trapping techniques for atoms allows the fabrication of genuinely microscopic Quantum wires and dots for individual particles. We discuss the physical features of a structure which can implement the controlled-not operation in Quantum logic. This consists of a network of tube-like microtraps and a laser that acts as a clock pulse. Our work discusses the influence of potential geometry, particle–particle interactions and Quantum statistics. The physical features are illustrated by wave packet simulations.
