Abstract

We review and compare several schemes for inducing precisely controlled quantum phases in quantum optical systems. We focus in particular on conditional dynamical phases, i.e. phases obtained via state-and time-dependent interactions between trapped two-level atoms and ions. We describe different possibilities for the kind of interaction to be exploited, including cold controlled collisions, electrostatic forces, and dipole–dipole interactions.
