Nonlinear pi phase shift for single fiber-guided photons

An optical resonator coupled to a single atom enables a medium that provides the maximum nonlinear phase shift of pi at the single-photon level, offering new possibilities for quantum technology.

A new scheme, based on positioning ultracold atoms at submicron distances from a gold surface and directing their fluorescence photons into surface plasmons, may enable the readout of quantum information.
