Abstract

Trapped single atoms are ideal for storing and manipulating quantum information. Thompson et al. (p. 1202, published online 25 April; see the Perspective by Keller) were able to control single atoms interacting coherently with a field mode of a photonic crystal cavity. An optical tweezer was used to trap the single atom, which enabled positioning of the atom in close proximity to the photonic crystal waveguide, coupling the atom to the optical mode of the cavity. Such coupling should prove useful in quantum measurement, sensing, and information processing.
