This report results from a contract tasking Ludwig-Maximilian University of Munich as follows In this new grant proposal, we specifically try to address important questions that have emerged out of our previous work and that should provide major advances for the field of quantum state engineering and quantum simulations, as well as quantum information processing. Possible applications also include non-classical matter wave field states that are especially useful for improving the performance of matter wave based atom interferometers. The grant proposal will be focused on research to be carried out on an existing and a completely novel experimental apparatus, focusing on two fundamental topics 1 Generation of robust multi-particle entanglement in optical lattices, with low decoherence rates as a resource for quantum information processing and improved atom interferometers and 2 The construction of a novel experimental apparatus with the possibility to address, observe and manipulate single atoms on single sites of an optical lattice. Based on our experience with previous experiments, we find these two topics to be of fundamental importance for future advances in this field.
