Noise-resistant optimal spin squeezing via quantum control. Physical Review A 93 (1): 013851-013857.http://nrs.harvard.edu/urn-3:HUL.InstRepos:12655535Entangled atomic states, such as spin squeezed states, represent a promising resource for a new generation of quantum sensors and atomic clocks. We demonstrate that optimal control techniques can be used to substantially enhance the degree of spin squeezing in strongly interacting many-body systems, even in the presence of noise and imperfections. Specifically, we present a time-optimal protocol that yields more than two orders of magnitude improvement with respect to conventional adiabatic preparation. Potential experimental implementations are discussed.en-USJournal Article2014-08-0510.1103/PhysRevA.93.013851
