Many experiments have demonstrated that Bose-condensed gases act as sources of coherent matter-waves with laser-like properties but it is only very recently that nonclassical quantum states have been observed i.e. number squeezed states produced by Josephson tunnelling and the Mott Insulator transition. In comparison to quantum optics with light, quantum atom optics offers the advantages of very efficient detection of individual particles and the states with well-defined numbers of atoms are less delicate. The highly number-squeezed states prepared in this way form the initial state required for quantum processing with neutral atoms. Our experiments will provide the data required to evaluate . such schemes e.g. to calculate the fidelity under given experimental conditions. During this project we will develop a novel experimental technique for reading out the position of the atoms that will be important for our future work on quantum information processing. An extra dimension to our work is the use of states whose interaction strength (scattering length) changes with the external magnetic field. This gives conditions where there is a large difference in the phase shifts accumulated by different magnetic states during a collision - this is a key feature required for a quantum logic gate.Keywords describing areas of proposal.Physics, Atom and Molecular
