In this talk I will describe recent experimental work in my group on quantum transport and control of Bose-Einstein condensates. In one experiment, we have achieved tight confinement of a rubidium BEC in an optical trap in one and two dimensions. An important feature of our work is that only a single 1-D condensate is produced, unlike other work with optical lattices where many replicas are created simultaneously. This feature, together with single-atom detection, are prerequisites for the experimental realization of a quantum tweezer for atoms. This idea, which we proposed several years ago, utilizes many-body quantum tunneling to extract single atoms on demand from a condensate. It serves as an example of many-body control and is the building block for scalable entanglement and quantum computing. In a second experiment, we have produced a BEC in sodium and have transferred the atoms to an optical elevator where the condensate will be used to study quantum reflection from surfaces and quantum transport in optical lattices.In this talk I will describe recent experimental work in my group on quantum transport and control of Bose-Einstein condensates.
