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 instrument can measure objects with apertures that range from 20 to 200mm or more, and consists of a laser diode, a conical mirror, and a miniature CCD or CMOS camera.
