One of the essential features of a quantum computer is a quantum ‘register’ of well–characterized qubits. Neutral atoms in optical lattices are a natural candidate for such a register. We have demonstrated a patterned–loading technique that can be used to load atoms into large arrays of tightly confined but optically resolvable lattice sites. We have also seen preliminary indications of the Mott–insulator transition, which provides a route for single–atom initialization of the individual sites. Combining the two experiments should allow for large arrays of individually addressable single atoms, a system which provides a starting point for further quantum computation studies.
