Complex Systems for Quantum Information

Complex systems provide advantages for the storage and processing of classical informa-tion. We address the question whether complex quantum systems can provide similar bene-fits for quantum information. First, we present a proof-of-principle implementation of a com-plex quantum system for quantum computation using a chain of ions in a trap. Second, we address the question of scalability focusing on complex systems of ultracold atoms in optical lattices and develop a method to characterize them by particle counting. Our results show that using the many-body features of quantum systems can be advantageous for quantum information processing.
