Research Description
Both laser-cooled atomic ions and neutral atoms in electromagnetic traps provide pristine quantum systems that can be engineered from the ground up to an unprecedented level of control. Atoms interacting with lasers offer unmatched coherence properties, deterministic entanglement generation and nearly perfect detection of individual quantum systems. In our lab we will use trapped ions and neutral atoms to assemble atom-by-atom quantum systems whose parameters can be tailored microscopically to investigate unexplored quantum many-body phenomena and tackle new ways of processing quantum information.
