document: Micro-optical realization of arrays of selectively addressable dipole traps : a scalable configuration for quantum computation with atomic qubits We experimentally demonstrate novel structures for the realization of registers of atomic qubits : We trap neutral atoms in one - and two-dimensional arrays of far-detuned dipole traps obtained by focusing a red-detuned laser beam with a microfabricated array of microlenses . We are able to selectively address individual trap sites due to their large lateral separation of 125 mu m . We initialize and read out different internal states for the individual sites . We also create two interleaved sets of trap arrays with adjustable separation , as required for many proposed implementations of quantum gate operations
